The practice of allowing family to be present during patient resuscitation or invasive procedures (Family Presence) is gaining acceptance in North America and the United Kingdom in controlled circumstances. Research into Family Presence has demonstrated multiple benefits for the patient, family and health care team. These advantages include helping the family to understand the severity of the illness/trauma and to see that appropriate attempts were undertaken to save their loved one. Family Presence can also facilitate improved communication between the health care team and family. In spite of evidence supporting Family Presence as a useful practice for patient, family and health care team, the use of Family Presence is uncommon within Australian emergency departments and hospitals. Clear expectations at organisational, governmental and professional levels are essential to effectively implement this approach. To be supported in the clinical area, the success of a Family Presence program requires an inclusive approach to program development. A critical component of a successful Family Presence program is a family facilitator who is adequately prepared for the role and committed to supporting the family during resuscitation or invasive procedures. Research exploring Family Presence in Australia is lacking and highlights the need for context specific research in this area. 相似文献

The study examined the effects of condition and communication partner on spontaneous and elicited communication in children with Autism Spectrum Disorder (ASD) in comparison to age matched typically developing children. Eighteen children participated in the study (nine children diagnosed with ASD and nine typically developing children). Each participant was video recorded for 2 h 15 min periods across two conditions (academic activity and free-time). The two conditions represented a naturalistic view of the children's environment. Spontaneous and elicited communication were further analysed in terms of verbal behavior functions including requests, mands for information, mands for attention, greetings, terminating an activity, comments/tacts, language of negotiation, specifying using autoclitics and reject. Communication partner was further analysed at two levels, peer and adult. There was no difference between the frequency of functions of communication emitted and diagnosis of the participant. There was a significant difference for communication partner, whereby the main communicative partner for children with ASD was an adult in contrast to typically developing children who spoke more to their peers. Typically developing children engaged in more spontaneous communication than children diagnosed with ASD. 相似文献

Chromium (Cr) is a human carcinogen and a potent DNA damaging agent.
Incubation of DNA with CrCl3 resulted in dose-dependent binding of Cr to
DNA and, at concentrations >20 microM, altered the electrophoretic
mobility of a 100 bp oligonucleotide. We also demonstrate that high
mobility group (HMG) proteins 1 and 2 bind Cr-damaged DNA (Cr-DNA). Protein
binding was lesion density-dependent, with maximal binding to DNA treated
with 100 microM CrCl3. HMG2 binds to Cr-DNA with a calculated Kd of
approximately 10(-9) M. These proteins also bound DNA obtained from
chromate-treated cells. These results suggest that the covalent attachment
of Cr to DNA induces alterations in DNA structure which are recognized by
HMG1 and HMG2. Therefore, these proteins may function as Cr-damaged DNA
recognition proteins in vivo and as a consequence of binding, may play a
role in directing the cellular response to Cr-DNA adduct formation.

35S-Captopril (50 mg/kg) administered i.v. to rats resulted in radioactivity being widely distributed into highly vascular tissues and into excretory organs. After oral administration of 14C-captopril (50 mg/kg), radioactivity in most tissues declined at a rate similar to that in blood. Concn. greater than those in blood were found only in kidney, liver and lung. The high concn. of 14C in kidney and liver were due to the excretory role of these organs. The high concn. of 14C in lung may be due to the high binding affinity of captopril to angiotensin-converting enzyme, present in large quantity in lung. 相似文献
