A Cross-Sectional Comparative Study of Nurses' and Family Members' Perceptions on Priority and Satisfaction in Meeting the Needs of Family Members at the Emergency Department

INTRODUCTION

Family members experience considerable physiological, psychological, and emotional pressure when accompanying a critically ill relative in the emergency department. The culture and context of care influence the needs of the family, and a thorough understanding of these needs by health care professionals is essential to providing patient- and family-centered care. This study aimed to compare nurses' and family members' perceptions of the priorities of family member needs and their satisfaction with meeting those needs in the emergency department.

METHODS

A comparative, cross-sectional descriptive study was conducted. Participants were 140 family members of patients receiving care and 122 nurses working in the emergency department in hospitals of Tabriz University of Medical Science, in Iran. The data were collected through Critical Care Family Needs Inventory-ED and analyzed with SPSS Statistics software.

RESULTS

Family members rated their care needs as significantly greater than did nurses (129.45 [31.5] vs 124.45 [24.8], P = .003). Families rated their needs as having been met significantly less than the nurses estimated (103.6 [17.6] vs 110.8 [19.61], P < .05).

DISCUSSION

The perceived importance of the patient's family's needs differed from the viewpoints of the patient's family members and the nurses. In addition, emergency nurses overestimated the extent to which family members' needs were met compared with family members. To more adequately gauge and meet the needs of family members, nurses need to acquire more knowledge about patient family needs in the emergency department.

The Nakata index and McGoon ratio: correlation with the severity of pulmonary regurgitation after the repair of paediatric tetralogy of Fallot

BACKGROUND

Pulmonary regurgitation is the most common complication after the complete repair of tetralogy of Fallot, and severe pulmonary regurgitation after surgery requires pulmonary valve replacement. In this retrospective observational, cross-sectional study, we included a total of 56 children aged 6 years or younger who underwent complete repair of TOF at Shahid Rajaei Cardiovascular Medical and Research Center in Tehran, Iran. Preoperative dual-source computed tomography was used to measure the McGoon ratio and Nakata index. The patients were divided into two groups based on the severity of postoperative pulmonary regurgitation, as estimated by trans-thoracic echocardiography: the severe pulmonary regurgitation group and the non-severe pulmonary regurgitation group. The McGoon ratio and Nakata index were then compared between the two groups.

RESULTS

When comparing the two groups, we found that the corrected right pulmonary artery diameter, main pulmonary artery diameter, and McGoon ratio in the non-severe pulmonary regurgitation group were higher than in the severe pulmonary regurgitation group. However, none of these differences were statistically significant. Additionally, other variables, including the corrected left pulmonary artery diameter and Nakata index, showed higher measurements in children with severe pulmonary regurgitation, but again, the differences were not statistically significant.

CONCLUSIONS

This study indicates that pulmonary arteries diameter, Nakata index, and McGoon ratio were not significantly correlated with the severity of pulmonary regurgitation after the complete repair of tetralogy of Fallot.

Serotonin axons of the neostriatum show a higher affinity for striatal than for ventral mesencephalic transplants: a quantitative study in adult and immature recipient rats

We previously showed that grafts of fetal ventral mesencephalic tissue are practically not innervated by host serotonin (5-HT) axons after implantation into the striatum of rats aged more than 14 days, at variance with transplants of cortical or striatal tissue into the adult striatum, which are well innervated by these axons. Using 5-HT immunohistochemistry and in vitro [3H]5-HT uptake/autoradiography, we have examined and quantified the innervation of ventral mesencephalic versus striatal grafts several months after implantation into the striatum of neonatal (postnatal day 5 or P5), juvenile (P15), and adult rats. Ventral mesencephalic grafts implanted in P5 rats received a moderate 5-HT innervation, while similar grafts implanted in P15 or adult recipients were almost free of any 5-HT fibers (-80%, compared to P5). The density of 5-HT innervation showed a tendency toward higher values in striatal than in ventral mesencephalic grafts (1.6-2 times higher in P5 and adult recipients; 4 times higher in P15 recipients). The difference was more striking, and significant, when only the true striatal portions of the striatal grafts were considered, i.e., DARPP-32-immunopositive areas (4-5 times higher in P5 and adult recipients; 10 times higher in P15 recipients). Accordingly, these DARPP-32-positive areas were also more densely innervated than the DARPP-32-negative zones of the same grafts (3 times higher at any age). The 5-HT innervation density also decreased with increasing age of the recipients in DARPP-32-positive, as well as DARPP-32-negative compartments of the striatal grafts (-75% in adults), but this decrease appeared more gradual (-50% in juveniles) than with mesencephalic grafts. It is concluded that the 5-HT axons innervating the neostriatum have a better affinity for striatal grafts than for ventral mesencephalic grafts or the nonstriatal portions of striatal grafts. In adulthood, the relative affinity of these axons for the different types of grafts is maintained, even though their growth capacity decreases irrespective of the target tissue considered. This experimental model may prove useful for the identification of the receptors and ligands that are responsible for target recognition by 5-HT axons and to test the possibility that the progressive decrease of axonal growth capacity from neonatal age to adulthood be related to a downregulation of such molecules.

Trophic and tropic effects of striatal astrocytes on cografted mesencephalic dopamine neurons and their axons

Astrocytes from the ventral mesencephalon and from the striatum respectively promote the dendritic and axonal arborization of dopamine (DA) neurons in vitro. To test this response in vivo, astrocytes in primary cultures from the neonatal cerebral cortex, ventral mesencephalon, or striatum were coimplanted with fetal ventral mesencephalic tissue into the intact or DA-denervated striatum of adult rats and these cografts examined after 3-6 months by tyrosine hydroxylase (TH) immunohistochemistry (intact recipients) or after 5-6 months by in vitro [3H]DA-uptake autoradiography (DA-denervated recipients). In contrast with single ventral mesencephalic grafts, all types of cograft displayed a rather uniform distribution of TH-immunoreactive perikarya. The average size of TH-immunoreactive cell bodies was not significantly different in cografts containing cortical or mesencephalic astrocytes and in single ventral mesencephalic grafts, but it was significantly larger in cografts containing striatal astrocytes. Nevertheless, the number of [3H]DA-labeled terminals in the DA-lesioned host striatum was clearly smaller with cografts of striatal astrocytes than with single mesencephalic grafts or with cografts containing cortical astrocytes. On the other hand, cografts of striatal astrocytes contained much higher numbers of [3H]DA-labeled terminals than the other types of graft or cograft. Thus, while cografted astrocytes in general influence the distribution of DA neurons within the graft, astrocytes from the neonatal striatum have a trophic effect on DA perikarya and a tropic effect on DA axons, keeping the latter within the graft.
