Expression of amphiregulin and epidermal growth factor receptor in human breast cancer: analysis of autocriny and stromal-epithelial interactions.

Amphiregulin (AR) and its receptor, epidermal growth factor receptor (EGFR), were evaluated by dual immunostaining in a series of 84 invasive ductal breast carcinoma specimens, 33 of which were from locally advanced inflammatory (T4d) cancer. Co-expression of AR and EGFR was always found in non-malignant breast tissues adjacent to tumours (24/24). Alternatively, expression of AR and EGFR was found in invasive epithelial tumour cells in 50% and 17.8% of specimens, respectively. In tumour stroma, 59.5% and 30.9% of specimens, respectively, were positively stained. By univariate analysis, AR and EGFR expression in invasive carcinomas was correlated with large tumour size, inflammatory carcinoma, node involvement, Bloom-Richardson (SBR) grade III, and absence of oestrogen receptor. EGFR expression in stromal cells was correlated with non-inflammatory carcinoma. A putative autocrine loop with AR and EGFR expression in invasive carcinoma was detected in 14.3% of cases. Stromal expression of AR and EGFR expression in invasive tumour cells was detected in 11.9% of cases and related to poor prognostic parameters. By multivariate analysis, AR expression in invasive tumour was strongly related to inflammatory carcinoma (p=0.005) and marginally related to SBR grade III (p=0.07). EGFR expression in invasive tumour and stromal cells was correlated with absence of oestrogen receptor and non-inflammatory carcinoma (p=0.002 and p=0.015, respectively).

Accuracy of a composite score using daily SAPS II and LOD scores for predicting hospital mortality in ICU patients hospitalized for more than 72 h.

UNLABELLED: In most databases used to build general severity scores the median duration of intensive care unit (ICU) stay is less than 3 days. Consequently, these scores are not the most appropriate tools for measuring prognosis in studies dealing with ICU patients hospitalized for more than 72 h. PURPOSE: To develop a new prognostic model based on a general severity score (SAPS II), an organ dysfunction score (LOD) and evolution of both scores during the first 3 days of ICU stay. DESIGN: Prospective multicenter study. SETTING: Twenty-eight intensive care units (ICUs) in France. PATIENTS: A training data-set was created with four ICUs during an 18-month period (893 patients). Seventy percent of the patients were medical (628) aged 66 years. The median SAPS II was 38. The ICU and hospital mortality rates were 22.7% and 30%, respectively. Forty-seven percent (420 patients) were transferred from hospital wards. In this population, the calibration (Hosmer-Lemeshow chi-square: 37.4, P = 0.001) and the discrimination [area under the ROC curves: 0.744 (95 % CI: 0.714-0.773)] of the original SAPS II were relatively poor. A validation data set was created with a random panel of 24 French ICUs during March 1999 (312 patients). MEASUREMENTS AND MAIN RESULTS: The LOD and SAPS II scores were calculated during the first (SAPS1, LOD1), second (SAPS2, LOD2), and third (SAPS3, LOD3) calendar days. The LOD and SAPS scores alterations were assigned the value "1" when scores increased with time and "0" otherwise. A multivariable logistic regression model was used to select variables measured during the first three calendar days, and independently associated with death. Selected variables were: SAPS II at admission [OR: 1.04 (95 % CI: 1.027-1.053) per point], LOD [OR: 1.16 (95 % CI: 1.085-1.253) per point], transfer from ward [OR: 1.74 (95 % CI: 1.25-2.42)], as well as SAPS3-SAPS2 alterations [OR: 1.516 (95 % CI: 1.04-2.22)], and LOD3-LOD2 alterations [OR: 2.00 (95 % CI: 1.29-3.11)]. The final model has good calibration and discrimination properties in the training data set [area under the ROC curve: 0.794 (95 % CI: 0.766-0.820), Hosmer-Lemeshow C statistic: 5.56, P = 0.7]. In the validation data set, the model maintained good accuracy [area under the ROC curve: 0.826 (95 % CI: 0.780-0.867), Hosmer-Lemeshow C statistic: 7.14, P = 0.5]. CONCLUSIONS: The new model using SAPS II and LOD and their evolution during the first calendar days has good discrimination and calibration properties. We propose its use for benchmarking and evaluating the over-risk of death associated with ICU-acquired nosocomial infections.

Influence of bone marrow graft lymphocyte subsets on outcome after HLA-identical sibling transplants.

OBJECTIVE: The aim of this study was to analyze bone marrow lymphocyte subsets and CD34 cell dose and their influence on the outcomes of bone marrow transplantation. MATERIALS AND METHODS: Forty-eight patients (median age 30 years, range 5-54) receiving HLA-identical sibling bone marrow transplantation for hematologic malignancies were analyzed. RESULTS: Median number (range) of nucleated cells and CD34+ cells infused were 2.4 (0.4-6.0) x 10(8)/kg and 3.5 (0.5-13.0) x 10(6)/kg, respectively. Probability of neutrophil recovery was 97%. In a multivariate analysis, time to neutrophil recovery was shortened when a higher number of CD3/CD8 cells was infused (> or =1.0 x 10(7)/kg) (hazard ratio [HR] = 2.13, p = 0.018); when the patient was female or had negative cytomegalovirus serology (HR = 2.03, p = 0.03; HR = 0.41, p = 0.009; respectively). The incidence of grade II to IV acute graft-vs-host disease (GVHD) was 47%. Infusion of >1 x 10(7) CD4 infused/kg increased the risk of acute GVHD (HR = 2.86, p = 0.03). Nineteen of 40 patients at risk experienced chronic GVHD, the risk of which was increased by diagnosis of chronic leukemia (p = 0.03), <2.0 x 10(8) nucleated cells infused/kg (p = 0.05), and a low number of all lymphocyte subsets, except CD19. Estimated 3-year survival rate was 54%. Risk of death was increased in patients receiving <3.5 x 10(6)CD34 infused/kg (HR = 0.37, p = 0.02). Only six patients relapsed. CONCLUSIONS: A high cell dose of CD3/CD8 is associated with faster neutrophil recovery, whereas a high cell dose of CD4+ cells increases the incidence of acute GVHD. A high number of nucleated cells and CD34+ cells infused was associated with decreased risk of chronic GVHD and improved survival, respectively.

Evaluating treatment strategies in chronic lymphocytic leukemia: use of quality-adjusted survival analysis.

To assess comparatively, in terms of quality-adjusted survival, three front-line treatments in patients with stage B- or C-chronic lymphocytic leukemia (CLL). To describe better and compare the survival after randomization of patients from the CLL90 trial that randomly compared ChOP (cyclophosphamide, doxorubicin, oncovin, prednisone), CAP (cyclophosphamide, doxorubicin, prednisone) and fludarabine in advanced CLL, we performed a quality-adjusted survival analysis. This consisted of defining four clinical states (toxicity, treatment free of toxicity, no treatment nor symptoms, relapse), then summing up the average times spent in each state weighted by utility coefficients that reflect relative value according to quality of life. The resulting quality-adjusted time without symptoms or toxicity (Q-TWIST) was compared between randomized groups, and sensitivity (threshold) analyses to the choice of utility coefficients was performed. Over 73 months after randomization, the fludarabine group gained a mean of 45 days of toxicity-free survival at CAP, and 61 days over ChOP. The mean TWIST was 27.05 months with CAP, 31.5 months with ChOP and 32.95 months with fludarabine. The threshold analyses showed that, whatever the utility weights, the mean Q-TWIST was always greater with ChOP or fludarabine as compared to CAP. Fludarabine was consistently a better treatment than ChOP, except in the unlikely case of high utility weights attributed to toxicity and low utility weights attributed to treatment. Nevertheless, from a clinical point of view, differences between ChOP and fludarabine were moderate or event slight (mean difference in TWIST of 1.45 months). We conclude that patients with advanced CLL have a moderate benefit in terms of Q-TWIST when treated with fludarabine over ChOP. These two treatments are always superior to CAP.

Results of unrelated umbilical cord blood hematopoietic stem cell transplant.

The number of umbilical cord blood transplants (UCBT) is increasing worldwide, and the purpose of Eurocord is to evaluate the results and compare the outcome of UCBT with allogeneic bone marrow transplants (BMT). Data have been reported to Eurocord by many transplant centers. Close links have been established with cord blood banks through Netcord. BMT data have been provided by transplant centers and also by the European Blood and Marrow Transplant (EBMT) and International Bone Marrow Transplant Registries (IBMTR). Eurocord has analyzed the outcome of unrelated UCBT from 121 transplant centers and 29 countries. The results have shown that survival with unrelated mismatched UCBT was comparable to that with unrelated BMT. Engraftment with cord blood was delayed, resulting in an increased incidence of early transplant complications. The incidence of acute and chronic graft-versus-host-disease (GVHD) was reduced with cord blood grafts even in HLA mismatched transplants and in adults. In patients with leukemia, the rate of relapse was similar to that after BMT. The overall event-free survival with UCBT was not statistically different when compared to BMT. In conclusion, this large registry study confirms the potential benefit of using umbilical cord blood hematopoietic stem cells for allogeneic transplants.

Influence of CD34(+) marrow cell dose on outcome of HLA-identical sibling allogeneic bone marrow transplants in patients with chronic myeloid leukaemia.

In order to study the influence of bone marrow CD34(+) cell dose on the outcome of allogeneic bone marrow transplantation (BMT), we analysed the results of BMT from HLA-identical siblings donors in 50 patients with chronic myeloid leukaemia (CML). The median numbers of nucleated cells (NC) and CD34(+) cells infused were 2.18 x 10(8)/kg (0.05-4.14 x 10(8)/kg) and 3.12 x 10(6)/kg (0.35-8.52 x 10(6)/kg), respectively. All patients engrafted. In univariate analysis, there was no correlation between the number of CD34(+) cells infused and the time to neutrophil recovery (P = 0.17). The Kaplan-Meier estimate of grade II-IV acute graft-versus-host disease (GVHD) at day 100 was 53 +/- 14% and 2-year survival was 46 +/- 15%. A number of CD34(+) cells infused greater than the median was the main factor increasing survival (P = 0.0006) and decreasing 100 day transplant-related mortality (P = 0.009). Patient-, disease- and transplant-related characteristics were not statistically different among patients receiving more or less than the median number of CD34(+) cells. The rate of infectious deaths was significantly higher in patients receiving less than 3.12 x 10(6) CD34/kg (48% vs 16%, P = 0.01). In a multivariable analysis, two factors associated with increased risk of death were advanced disease status at transplant (HR: 2.5 (95% CI: 1.09-5.75), P = 0.03) and a lower number of marrow CD34(+) cells infused/kg (HR: 4.55 (95% CI: 1.87-10.90), P = 0.0008).

Evaluating treatment strategies in advanced Waldenström macroglobulinemia: use of quality-adjusted survival analysis.

A randomized phase II multicenter clinical trial comparing the efficacy of fludarabine (FAMP) to that of the association of cyclophosphamide, doxorubicin and prednisone (CAP) in 92 patients with Waldenstrom's macroglobulinemia in first relapse or with primarily resistant disease, was conducted on the behalf of the 'Groupe Coopératif Macroglobulinémie'. The main analysis of this study failed to demonstrate a clear cut benefit of FAMP in terms of overall survival (OS), although a significant benefit in terms of time to disease progression and event-free survival (EFS) was noted. In this rare disorder, where few randomized trials have been conducted, we took advantage of this trial to assess treatment differences while integrating quality of life considerations. We thus performed a quality-adjusted survival analysis, using the quality-adjusted time without symptoms or toxicity (Q-TWiST) approach. Four health states differing in terms of quality of life (QoL) were defined, namely treatment-related toxicity, treatment free of toxicity, no treatment or symptoms, and relapse. The average time spent in these health states (TOX, CT, TWiST and REL, respectively) were then weighted by utility coefficients reflecting relative QoL value according to that of TWiST and summed up giving the so-called Q-TWiST. No difference was found between randomized groups in terms of mean CT. Mean TOX in the two groups were similarly close except when considering alopecia as a relevant toxic event. By contrast, mean TWiST was 5.9 months longer in the FAMP group than in the CAP group (P = 0.006). Unsurprisingly, given the absence of difference in OS but the difference in EFS in favor of the FAMP group, mean REL was increased by 6.8 months in the CAP group (P = 0.047). As a result, benefit of FAMP in terms of average Q-TWiST only relied on the value of the utility coefficient attributed to REL (U(REL)), with a significant benefit when UREL ranged from 0 to 0.28, ie in patients undergoing poor QoL after relapse, which is likely.

Virologic and immunologic parameters that predict clinical response of AIDS-associated Kaposi's sarcoma to highly active antiretroviral therapy.

The purpose of the work was to assess the predictive value of biologic factors on the efficacy of highly active antiretroviral therapy alone or combined with chemotherapy on AIDS-associated Kaposi's sarcoma. Twenty-six AIDS-Kaposi's sarcoma patients who started therapy with protease inhibitors were investigated. No baseline chemotherapy was associated with less severe initial clinical status. Median follow-up was 652 d. The main outcome measures were as follows: best Kaposi's sarcoma clinical response; Kaposi's-sarcoma-associated herpesviral load in peripheral blood mononuclear cells using real-time quantitative polymerase chain reaction (non-detectable if less than 100 copies per microg); human immunodeficiency viral charge in plasma (non-detectable if less than 200 copies per ml); and CD4 lymphocyte count. Time to undetectable Kaposi's-sarcoma-associated herpesviral load, time to undetectable human immunodeficiency viral charge, and time to CD4 >or= 150 per microl were also recorded over time, from 2 mo measurements. Patients were staged according to the AIDS Clinical Trials Group-based tumor, immune, systemic staging system criteria. At baseline, Kaposi's sarcoma was progressive for 25 (96%) of the 26 enrolled patients. Complete or partial response to highly active antiretroviral therapy alone or combined with chemotherapy was achieved in 22 patients (85%). Median time to clinical response was estimated at 251 d. Clinical response was faster in patients without chemotherapy at baseline (p = 0.003) as well as in patients not previously treated with reverse transcriptase inhibitors (p = 0.0012). Using univariable analyses, predictive factors of clinical response were undetectable Kaposi's-sarcoma-associated herpesviremia (p = 0.013), undetectable human immunodeficiency viremia (p = 0.03), and relative variation of CD4 lymphocytes (p = 0.004). Using multivariable analysis, undetectable Kaposi's-sarcoma-associated herpesviremia (p = 0.009) and relative variation of CD4 (p = 0.005) were independently selected as having a predictive value for clinical response. Occurrence of nondetection of either Kaposi's-sarcoma-associated herpesvirus or human immunodeficiency virus was not associated with baseline CD4 value. Kaposi's-sarcoma-associated herpesvirus quantitative viral charge is an independent predictive factor of the efficacy of highly active antiretroviral therapy on AIDS-Kaposi's sarcoma. Our results support immune reconstitution as a mechanism of response of Kaposi's sarcoma to highly active antiretroviral therapy.

Results of unrelated umbilical cord blood hematopoietic stem cell transplantation.

The number of umbilical cord blood transplants is increasing worldwide. The purpose of Eurocord is to evaluate the results and to compare the outcome of umbilical cord blood transplants with allogeneic bone marrow transplants. Data have been reported to Eurocord by multiple transplant centers. Close links have been established with the cord blood banks through Netcord. Bone marrow transplant data have been provided by transplant centers and also through the European Group for Blood and Marrow Transplantation (EBMT) and International Bone Marrow Transplant Registries (IBMTR). Eurocord has analyzed the outcome of unrelated umbilical cord blood transplants from 121 transplant centers and 29 countries. The results showed that survival with unrelated mismatched umbilical cord blood transplants was comparable to that with unrelated bone marrow transplants. Engraftment with cord blood was delayed, resulting in an increased incidence of early transplant complications. The incidence of acute and chronic graft-vs.-host disease was reduced with cord blood grafts even in human leukocyte antigen (HLA)-mismatched transplants and in adults. In patients with leukemia, the rate of relapse was similar to the rate of relapse after bone marrow transplant. The overall event-free survival with umbilical cord blood transplantation was not statistically different when compared to bone marrow transplants. This large registry study confirms the potential benefit of using umbilical cord blood hematopoietic stem cells for allogeneic transplants.

Routine exploratory thoracentesis in ICU patients with pleural effusions: results of a French questionnaire study.

PURPOSE: The purpose of this study was to report the opinions of intensivists regarding pleural effusions in patients in the intensive care unit (ICU). MATERIALS AND METHODS: Questionnaires were sent to 1,032 intensivists, who were members of the French Society of Critical Care. RESULTS: Four hundred thirty-one questionnaires (41.7%) were returned. Overall, the respondents' estimated the incidence of pleural effusion in ICU patients to be 22.19 +/- 17%, whereas 37 +/- 27% considered that exploratory thoracentesis was likely to determine the cause of the effusion, and 17.36 +/- 16% considered that its results were likely to result in a change in their therapeutic attitude. Sixty-five (15%) physicians, chiefly pulmonologists, performed exploratory thoracentesis routinely (Group 1). Compared with those who did not perform routine thoracentesis (Group 2), they ascribed a higher proportion of pleural effusions to infection (31.3% vs. 13.5%) and were more likely to consider that exploratory thoracentesis had a diagnostic and therapeutic contribution (51.2% vs. 34% and 23% vs. 16%, respectively). In addition to the respiratory medicine subspecialty, the practice of routine exploratory thoracentesis was significantly related to seniority, to the frequency of the suspicion of an infectious cause in the physician's practice, and to his or her appreciation of the risks associated with exploratory thoracentesis. Physicians from Group 1 were also more likely to describe exploratory thoracentesis as a noninvasive procedure. CONCLUSIONS: The beliefs and attitudes of intensivists regarding pleural effusions and exploratory thoracentesis are divergent. This may be due to the lack of precise guidelines on the topic and prompt the design of further studies to establish precisely the epidemiology and causes of pleural effusions in ICU patients.

The tolerance and efficacy of interferon-alpha in haemodialysis patients with HCV infection: a multicentre, prospective study.

BACKGROUND: A prospective multicentre study was initiated in HCV-infected haemodialysis patients to assess the tolerance and efficacy of alpha-2b interferon. METHODS: We had planned to include 120 patients with HCV RNA detectable by polymerase chain reaction (PCR) (Amplicor Roche) and histologically documented chronic hepatitis. The dose of alpha-interferon was 3 million units (MU) three times weekly (TTW), to be reduced to 1.5 MU TTW in case of side-effects. Tolerance was evaluated monthly; virological efficacy was evaluated by PCR. A liver biopsy was performed at month 18 (M18). RESULTS: (a) TOLERANCE: After 37 patients had been included, the study was discontinued by the promoting institution because of severe side-effects requiring that treatment be stopped in 19 patients. The side-effects were: cardiac (4) neuropsychiatric (2), digestive (3), acute necrosis of the graft (1), severe asthenia (9), minor side-effects were observed in 22 patients. A complete 12-month course was completed in 12 patients for the 3 MU TTW dose and in six patients for the 1.5 MU TTW reduced dose. Normal ALT level (OR, 0.16; CI 95%, 0.03-0.89) at inclusion was associated with interruption of treatment (univariate analysis). (b) EFFICACY: Sustained virological response was observed in only seven (18.9%), of the 18 patients who completed the treatment (38%). Increased ALT at inclusion (OR, 1.04; CI 95%, 1.01-1.09) and cumulated doses of interferon (OR, 1.01; CI 95%, 1.004-1.026) were jointly associated with a sustained response, while positive PCR at M2 was strongly predictive of treatment failure. CONCLUSION: Tolerance of interferon is poor in haemodialysis patients. Sustained response is fairly high in patients who have 12 months of treatment and seems to be based on the immune status of the patients (ALT) and the cumulative doses of interferon.

Improved survival in cancer patients requiring mechanical ventilatory support: impact of noninvasive mechanical ventilatory support.

OBJECTIVE: When a cancer patient becomes critically ill, mechanical ventilation (MV) is often considered futile. However, recent studies have found that outcomes of critically ill cancer patients have been improving over the years and that classic predictors of high mortality have lost their relevance. DESIGN: We retrospectively determined outcomes and predictors of 30-day mortality in 237 mechanically-ventilated cancer patients admitted to the intensive care unit (ICU). PATIENTS: The 132 (55.7%) patients who were admitted between 1990 and 1995 were compared with 105 (44.3%) patients who were admitted between 1996 and 1998. The malignancy was leukemia/lymphoma in 119 (50.3%) patients, myeloma in 50 (21%), and a solid tumor in 68 (28.7%). Forty-two (17.7%) patients had bone marrow transplantation, and 91 (38.4%) were neutropenic. Median Simplified Acute Physiology Score II (SAPS II) was 58 (range, 40-75). Reasons for MV were acute hypoxemic respiratory failure in 148 (62.5%) patients, coma in 54 (22.8%), and cardiogenic pulmonary edema in 35 (14.7%). Conventional MV was used first in 189 (79.8%) patients, and noninvasive MV (NIMV) was used in 48 (20.2%). Overall mortality rate was 72.5% (172 deaths). RESULTS: Logistic regression identified three variables associated with mortality: ICU admission between 1996 and 1998 (odds ratio [OR], 0.24; 95% confidence interval [CI], 0.12-0.50) and the use of NIMV (OR, 0.34; 95% CI, 0.16-0.73) were protective, and the SAPS II was aggravating (OR, 1.04 per point; 95% CI, 1.02-1.06). To better define the impact of NIMV, we performed a pairwise-matched exposed-unexposed analysis. Forty-eight patients who did and 48 who did not receive NIMV as the first ventilation method were matched for SAPS II, type of malignancy, and period of ICU admission. Crude ICU mortality rates from exposed patients and controls were 43.7% and 70.8%, respectively. NIMV remained protective from mortality after adjustment for matching variables (OR, 0.31; 95% CI, 0.12-0.82). CONCLUSION: Our results confirm that mortality has improved over the past decade in critically ill cancer patients, even those who require MV, and suggest that this may be, in part, because of a protective effect of NIMV.

French intensivists do not apply American recommendations regarding decisions to forgo life-sustaining therapy.

OBJECTIVE: Recommendations for making and implementing decisions to forgo life-sustaining therapy in intensive care units have been developed in the United States, but the extent that they are realized in practice has yet to be measured. DESIGN: Prospective, multicenter, 4-wk study. For each patient with an implemented decision to forgo life-sustaining therapy, the deliberation and decision implementation procedures were recorded. SETTING: French intensive care units. PATIENTS: All consecutive patients admitted to 26 French intensive care units. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 1,009 patients admitted, 208 died in the intensive care unit. A decision to forgo life-sustaining therapy was implemented in 105 patients. The number of supportive treatments forgone was 2.3 +/- 1.7 per patient. Decisions to forgo sustaining therapy were preceded by 3.5 +/- 2.5 deliberation sessions. Proxies were informed of the deliberations in 62 (59.1%) cases but participated in only 18 (17.1%) decisions. The patient's perception of his or her quality of life was rarely evaluated (11.5%), and only rarely did the decision involve evaluating the patient's wishes (7.6%), the patient's religious values (7.6%), or the cost of treatment (7.6%). Factors most frequently evaluated were medical team advice (95.3%), predicted reversibility of acute disease (90.5%), underlying disease severity (83.9%), and the patient's quality of life as evaluated by caregivers (80.1%). CONCLUSIONS: A decision to withhold or withdraw life-sustaining therapy was implemented for half the patients who died in the French intensive care units studied. In many cases, the decision was taken without regard for one or more factors identified as relevant in U.S. guidelines.

Symptoms of anxiety and depression in family members of intensive care unit patients: ethical hypothesis regarding decision-making capacity.

OBJECTIVE: Anxiety and depression may have a major impact on a person's ability to make decisions. Characterization of symptoms that reflect anxiety and depression in family members visiting intensive care patients should be of major relevance to the ethics of involving family members in decision-making, particularly about end-of-life issues. DESIGN: Prospective multicenter study. SETTING: Forty-three French intensive care units (37 adult and six pediatric); each unit included 15 patients admitted for longer than 2 days. PATIENTS: Six hundred thirty-seven patients and 920 family members. INTERVENTIONS: Intensive care unit characteristics and data on the patient and family members were collected. Family members completed the Hospital Anxiety and Depression Scale to allow evaluation of the prevalence and potential factors associated with symptoms of anxiety and depression. MEASUREMENTS AND MAIN RESULTS: Of 920 Hospital Anxiety and Depression Scale questionnaires that were completed by family members, all items were completed in 836 questionnaires, which formed the basis for this study. The prevalence of symptoms of anxiety and depression in family members was 69.1% and 35.4%, respectively. Symptoms of anxiety or depression were present in 72.7% of family members and 84% of spouses. Factors associated with symptoms of anxiety in a multivariate model included patient-related factors (absence of chronic disease), family-related factors (spouse, female gender, desire for professional psychological help, help being received by general practitioner), and caregiver-related factors (absence of regular physician and nurse meetings, absence of a room used only for meetings with family members). The multivariate model also identified three groups of factors associated with symptoms of depression: patient-related (age), family-related (spouse, female gender, not of French descent), and caregiver-related (no waiting room, perceived contradictions in the information provided by caregivers). CONCLUSIONS: More than two-thirds of family members visiting patients in the intensive care unit suffer from symptoms of anxiety or depression. Involvement of anxious or depressed family members in end-of-life decisions should be carefully discussed.

Compliance with triage to intensive care recommendations.

DESIGN: Recommendations for triage to intensive care units (ICUs) have been issued but not evaluated. SETTING: In this prospective, multicenter study, all patients granted or refused admission to 26 ICUs affiliated with the French Society for Critical Care were included during a 1-month period. Characteristics of participating ICUs and patients, circumstances of triage, and description of the triage decision with particular attention to compliance with published recommendations were recorded. RESULTS: During the study period, 1,009 patients were and 283 were not admitted to the participating ICUs. Refused patients were more likely to be older than 65 yrs (odds ratio [OR], 3.53; confidence interval [CI], 1.98-5.32) and to have a poor chronic health status (OR, 3.09; CI, 2.05-4.67). An admission diagnosis of acute respiratory or renal failure, shock, or coma was associated with admission, whereas chronic severe respiratory and heart failure or metastatic disease without hope of remission were associated with refusal (OR, 2.24; CI, 1.38-3.64). Only four (range, 0-8) of the 20 recommendations for triage to ICU were observed; a full unit and triage over the phone were associated with significantly poorer compliance with recommendations (0 [0-2] vs. 6 [2-9], p =.0003; and 1 [0-6] vs. 6 [1-9], p <.0001; respectively). CONCLUSION: Recommendations for triage to intensive care are rarely observed, particularly when the unit is full or triage is done over the phone. These recommendations may need to be redesigned to improve their practicability under real-life conditions, with special attention to phone triage and triaging to a full unit.

Induction of labour with a viable infant: a randomised clinical trial comparing intravaginal misoprostol and intravaginal dinoprostone.

OBJECTIVE: To compare the efficacy and safety of vaginal misoprostol (50 microg) with vaginal dinoprostone. DESIGN: Double-blind randomised trial. SETTING: Obstetrics Department, Poissy Hospital, France. PARTICIPANTS: 370 patients with medical indications for induction of labour. OUTCOME MEASURES: Vaginal deliveries within 24 hours, as well as time to vaginal deliveries, caesarean rates, costs, and fetal, neonatal and maternal condition. RESULTS: Compared with vaginal dinoprostone, vaginal misoprostol resulted in greater efficacy in several areas: vaginal delivery within 24 hours; time to vaginal delivery; and vaginal delivery within 12 hours. There was a non-significant increase in the caesarean section rate for fetal distress in the misoprostol group, but fewer caesarean sections for failed induction. Fetal tolerance was similar in the two groups, although significantly more neonates had a cord pH <7.20 and (non-significantly) none had meconium stained amniotic fluid in the misoprostol group. The incidence of poor neonatal outcome was similar in both groups. Subgroup analysis by indication for induction showed that the higher rates of arterial cord pH <7.20 and of meconium-stained amniotic fluid with misoprostol persisted only in possible fetal compromise. Poor neonatal outcome was less frequent in the misoprostol group in cases of induction for non-fetal indications. CONCLUSIONS: Vaginal misoprostol resulted in successful and earlier induction of labour more often than dinoprostone, but the safety of misoprostol raises some concern in potentially compromised infants. Misoprostol should be preferred to dinoprostone in cases of induction for non-fetal indications.
