RESUMO
BACKGROUND: Neonatal intensive care unit (NICU) is one of the accident-prone settings in the health-care system. There is a series of structural and process threats to the safety of infants hospitalized in this unit, which can be prevented by taking the right actions. For this purpose, developing standards based on current knowledge, available resources, and the context that provides care can determine patient injury prevention requirements. Likewise, it can be a source for national development and application of related guidelines and protocols. This study aims to develop patient safety standards in the NICUs of Iran. MATERIALS AND METHODS: This mixed-methods study will apply the exploration, preparation, implementation, and sustainment framework to develop patient safety standards. In each phase of this framework, a set of activities take place. Exploration is based on the world health organization model to develop standards. Determining the validity and applicability of standards will be done in Phase 2 (Preparation) and Phase 3 (Implementation), respectively. Since the long-term effects are not desired, the fourth phase (Sustainment) will not be considered. DISCUSSION: Patient safety standards from this study will contribute to efficient and effective, equitable, and high-quality health-care delivery. The application of them will further promote patient safety and the quality of medical care in Iranian NICUs.
RESUMO
The kinetics and mechanism of the reaction of OH with furan have been theoretically studied. The potential energy surface for each possible pathway has been investigated by employing DFT, G3MP2, and CCSD methods. The potential energy surface consists of one hydrogen-bonded complex and two energized intermediates. Three different pathways are suggested to be possible for the title reaction. The most probable channel is the hydroxyl radical addition to the C(2) position on the furan ring to cause the ring-opening process. The two other pathways are hydrogen abstraction from one of the C(2) or C(3) position on furan and hydroxyl radical substitution at the C(2) or C(3) position on furan. Abstraction and substitution channels are minor paths at low temperature, but they become comparable with addition channels at high temperature. Addition and substitution reactions proceed via formation of two energized intermediates, Int(1) and Int(2). Multichannel RRKM-TST calculations have been carried out to calculate the individual and overall rate constants for addition and substitution reactions. Direct-dynamics canonical variational transition-state theory calculations with small curvature approximation for tunneling were carried out to study hydrogen abstraction pathways.

BACKGROUND: Preterm infants constitute a large proportion of the newborn population in the neonatal intensive care units (NICUs). Parents, as the main members of the care team, are not adequately supported as the focus is chiefly on infant care. The present study aimed to evaluate the effect of a family support intervention on the stress levels among the parents of preterm infants in NICU. MATERIALS AND METHODS: In this quasi-experimental study, convenience sampling method was used to select 50 parents of preterm infants. The subjects were allocated to two groups of intervention and control (n = 25 pairs in each). While the control group received routine care, the intervention group benefitted from a two-stage family support program (including informational and observational phases in the first stage and emotional supportive intervention in the second). The Parental Stressor Scale-NICU (PSS-NICU) was completed by both fathers and mothers of the two groups (before and after intervention). Descriptive and inferential statistics were employed to analyze data in SPSS version 18. RESULTS: Before the intervention, the mean total scores of PSS-NICU and also the mean scores of its three subscales were not significantly different between the two groups. However, after the intervention, significant differences were observed between the two groups. The scores of the intervention group showed significant reduction following the intervention, but such a difference was not detected in the control group. CONCLUSIONS: Apparently, early educational and emotional support for parents of preterm infants decreased their stress. Similar interventions may thus be effective in empowering parents for caring of their infant and playing their parental role.
