The public's attitude and perception concerning witnessed cardiopulmonary resuscitation.

OBJECTIVE: For healthcare providers, witnessed cardiopulmonary resuscitation (CPR) is controversial. However, little is known about the public's stance on this issue. This study was performed to develop insight concerning the general public's thoughts about witnessed CPR. DESIGN: A random telephone survey. SETTING: Rural southwest Pennsylvania. SUBJECTS: Four hundred and eight respondents, >/=18 yrs old, residing in Conemaugh Health System's Memorial Medical Center's service area. INTERVENTIONS: : Demographic information was gathered concerning the respondents, who rated their level of agreement with questions concerning witnessed resuscitation. MEASUREMENTS AND MAIN RESULTS: Of the respondents, 49.3% desired to be present while CPR is performed on a loved one. Respondents desiring CPR were more apt to believe that significant others have a right to be present during CPR (p = .010) and want significant others present with them while undergoing CPR than those declining CPR (p < .001). Respondents desiring CPR felt more strongly that the presence of family or friends during CPR would benefit the patient (p = .022). The desire to be present in the room with a loved one during CPR did not reach statistical significance (p = .275) between the two groups, nor did the belief that that being present would benefit family and friends (p = .093). Of the respondents, 43% believed that the physician should have the most authority in making decisions about witnessed resuscitation, 40% believed that the patient should have the most authority, and 17% believed that family and friends should have the most authority (p < .001). Those who believed that family and friends should have the most authority were more favorable toward witnessed resuscitation than were those who believed that either the patient or the physician should have the most authority. CONCLUSIONS: This study offers insights into the public's attitude concerning witnessed resuscitation. A large segment of the population desires the presence of significant others during CPR and conversely want to be with loved ones during CPR. Further studies should investigate the public's attitude in more diverse settings, and formal programs to accommodate those who wish to remain together during CPR should be developed.

Increased microchimeric CD4+ T lymphocytes in peripheral blood from women with systemic sclerosis.

Recent studies have demonstrated the presence of microchimeric cells in peripheral blood and skin lesions from patients with systemic sclerosis (SSc). In a previous study we found that some peripheral blood CD3+ cells from female patients with SSc contained male DNA. Here, peripheral blood samples from 47 patients with SSc (30 with diffuse cutaneous SSc and 17 with limited cutaneous SSc) and 22 healthy controls were sorted for CD4+ and CD8+ T cells. Both positively and negatively selected populations were analyzed for male DNA by quantitative PCR. Analysis of Y chromosome sequences in the sorted cells demonstrated the presence of microchimerism in 82.9% of SSc patients compared to 63.6% of controls. The numbers of CD4+ and CD8+ T cells were found to be significantly higher in the SSc patients than in controls. Furthermore, patients with dcSSc were observed to have significantly more CD4+ microchimeric T cells than the controls. In the CD8+ T-cell population, there was a trend toward more microchimeric cells in the patients but this did not reach significance. These results support the hypothesis that microchimeric CD4+ T cells may be involved in the pathogenesis of SSc.
