[Suicide attempts by young adolescents: epidemiological characteristics of 517 15-year-old or younger adolescents admitted in French emergency departments]. / Tentatives de suicide: étude descriptive d'une cohorte de 517 adolescents de moins de 15 ans et 3 mois.

Adolescents who attempt suicide are a major concern. A growing body of literature seeks to explain this phenomenon and to identify its predictive factors, but relatively little information is available and children and adolescents under 15 years of age who present to general hospitals because of a suicide attempt. This study aimed to describe the demographic, social, medical, and psychological characteristics of a large sample of 517 French adolescents aged not more than 15 years 3 months. A second purpose was to measure observance of psychological care in a 1-year follow-up. Third, we aimed to document the reattempt rate during the follow-up in this population of young adolescents. Following the French official recommendations, a systematic 72-h hospitalization as well as a somatic, social, and psychological assessment was proposed to every suicide attempter after his or her admission to the emergency department. The adolescent was followed for 1 year after the suicide attempt, called the index episode. This follow-up was organized by two physicians, one of whom was not associated with the care of any of the patients. It consisted in seeking regular information as well as organization and/or optimization of the patient's psychological care, which was delivered in dedicated structures for adolescents, in outpatient care by a psychiatrist, or in an adolescent psychiatric inpatient care unit. In case of a repeated suicide attempt or persistence of alarming symptoms, this follow-up was prolonged for 1 more year. Patient data were compiled by experienced clinicians during initial assessment and alongside the 1-year follow-up through patient self-reports, but also through interviews with informants (family members, social professionals) and clinical sources (general practitioner, psychiatrist, etc.). The areas covered were the characteristics of the index episode, those of the population at the time of the index episode, as well as those of the 1-year follow-up including observance to the care and potential repetition of the suicide attempt. The mean age was 14 years with a minimum of 7 years 9 months. The vast majority of the population was female (86.1%), less than one-third lived with both parents, and 27% had academic problems. The most frequent means of suicide attempt was medication (83.9%), 92.6% of adolescents were hospitalized following the index episode, only 7.5% of them were admitted to adolescent psychiatric unit inpatient care following the initial care. Psychiatric evaluation was documented for 93.3% of the adolescents. Half (n=222) had at least one symptom of a psychiatric disorder. One-year follow-up data were available for 394 adolescents: 40 had not yet completed the year and 83 were lost to follow-up. Among the analyzable population of 391 adolescents, 35.3% were optimally observant of the care proposed and 21.4% did not observe treatment. Fifty-nine youths (15%) were referred to the hospital because of a repeated suicide attempt. Two of the patients who repeated the suicide attempt within the year had died. The findings from this study are informative with regard to prevention and intervention efforts with suicidal young and very young adolescents. First, repetition of the suicide attempt in young adolescents is not rare since nearly 15% of the cohort were repeaters within the year following the index episode. Nevertheless, intensive care and follow-up resulting in good attendance appeared to have a positive impact on the repetition of the suicide attempt.

Iodine biokinetics and radioiodine exposure after recombinant human thyrotropin-assisted remnant ablation in comparison with thyroid hormone withdrawal.

CONTEXT: A few prospective studies have evaluated the use of recombinant human TSH (rhTSH) for radioiodine remnant ablation. OBJECTIVE: Our objective was to compare the effects of the both TSH regimens on iodine biokinetics in the thyroid remnant, dosimetry, and radiation protection. DESIGN: We conducted a prospective randomized study. MATERIALS AND METHODS: Eighty-eight patients were enrolled for radioiodine ablation to either the hypothyroid or rhTSH arms. A whole-body scan was performed at 48 and 144 h after therapy. Dose rates were assessed at 24, 48, and 144 h. Urinary samples were obtained during the first 48 h. Thyroglobulin was assessed before and after therapy. Iodine biokinetics in the remnants were calculated from gamma-count rates. Radiation-absorbed dose was calculated using OLINDA software. Exposure estimation was based on a validated model. RESULTS: The effective half-life in the remnant thyroid tissue was significantly longer after rhTSH than during hypothyroidism (P = 0.01), whereas 48-h (131)I uptakes and residence times were similar. After therapy, thyroglobulin release (a marker of cell damage) was lower in the rhTSH arm. The mean total-body effective half-life and residence time were shorter in patients treated after rhTSH. Residence time was also lower for the colon and stomach. Absorbed dose estimates were lower in the rhTSH arm for the lower large intestine, breasts, ovaries, and the bone marrow. Dose rates at the time of discharge were lower in the rhTSH group with a reduction in cumulative radiation exposure to contact persons. CONCLUSIONS: In comparison with thyroid hormone withdrawal, rhTSH is associated with longer remnant half-life of radioactive iodine while also reducing radiation exposure to the rest of the body and also to the general public who come in contact with such patients.

Quality of life changes and clinical outcomes in thyroid cancer patients undergoing radioiodine remnant ablation (RRA) with recombinant human TSH (rhTSH): a randomized controlled study.

BACKGROUND: Recombinant human TSH (rhTSH) has become the modality of choice for radioiodine remnant ablation (RRA) in low-risk thyroid cancer patients. AIMS AND METHODS: The aims of the present prospective randomized study were to evaluate the impact of TSH stimulation procedure (hypothyroidism vs. rhTSH) on quality of life (QoL) of thyroid cancer patients undergoing RRA and to evaluate efficacy of both procedures. L-T4 was initiated in both groups after thyroidectomy. After randomization, L-T4 was discontinued in hypothyroid (hypo) group and continued in rhTSH group. A measure of 3.7 GBq of radioiodine was given to both groups. The functional assessment of chronic illness therapy-fatigue (FACIT-F) was administered from the early postoperative period to 9 months. Socio-demographic parameters, anxiety and depression scales were also evaluated (CES-D, BDI and Spielberger state-trait questionnaires). At 9 months, patients underwent an rhTSH stimulation test, diagnostic (131)I whole body scan (dxWBS) and neck ultrasonography. RESULTS: A total of 74 patients were enrolled for the study. There was a significant decrease in QoL from baseline (t0) to t1 (RRA period) in the hypothyroid group with significant differences in FACIT-F TOI (P < 10(-3)), FACT-G total score (P = 0.005) and FACIT-F total score (P = 0.003). By contrast, QoL was preserved in the rhTSH group. In the multivariate analysis, FACIT-TOI changes were only affected by the modality of TSH stimulation performed for RRA. From 3 to 9 months, changes of QoL scales and subscales were no longer statistically different in both groups of patients. Based on serum rhTSH-stimulated Tg alone (Tg < 0.8 microg/l, BRAHMS Tg Kryptor), no difference in ablation success was observed between rhTSH and hypothyroidism groups, 91.7% and 97.1%, respectively. A higher rate of persistent thyroid remnants was observed in the rhTSH arm, although in most cases uptake was < 0.1% and of no clinical significance. CONCLUSIONS: rhTSH preserves QoL of patients undergoing RRA with similar rates of ablation success compared to hypothyrodism. However, there is a wide heterogeneity in the clinical impact of hypothyroidism.

Healthy sibling donor anxiety and pain during bone marrow or peripheral blood stem cell harvesting for allogeneic transplantation: results of a randomised study.

This study reports the first comparison of healthy donor subjective well-being during two alternative procedures of hematopoietic stem cells harvesting for allogeneic transplantation. Among the 105 donors included between September 1996 and October 1998 in the SFGM French randomised trial aiming to compare allogeneic bone marrow (BM) transplantation and blood cell (BC) transplantation, 64 donors (33 in BC and 31 in BM groups) were relevant for the analysis. They had received a set of self-administered questionnaires to complete during the collection process, aiming to measure anxiety (assessed using the Spielberger's State-Trait Anxiety Inventory) and pain induced by the procedure (evaluated using a visual analogical scale). Results showed that no harvest procedure is free from pain even if none was more painful than the other. Levels of anxiety before the collection procedure were high in both groups and significantly so for BC donors. Although BC collection induces at least similar levels of pain and anxiety as does BM collection, they were of a different kind, and the short-term impact of G-CSF stimulation on the well-being of BC donors has to be taken into account in improving quality of care in the allogeneic setting.

[Economic evaluation of blood stem-cells autologous transplantation]. / L'évaluation économique de l'autogreffe de cellules souches du sang périphérique.

Economic evaluation of autologous peripheral blood stem cell (PBSC) transplantation certainly played a role in the very fast substitution from bone marrow to BC autograft. Economic evaluation is still ongoing about the optimization of the procedure by assessing the cost-effectiveness ratio of each new improvement of the technique. Among these improvements we present the administration of high dose CD34+ cells, the delayed administration of G-CSF and the outpatient management of post-graft follow-up. It is still very rare in the field of health economics to notice such an early and ongoing economic evaluation of an innovation.

Randomized trial of bone marrow versus lenograstim-primed blood cell allogeneic transplantation in patients with early-stage leukemia: a report from the Société Française de Greffe de Moelle.

PURPOSE: To compare hematologic recovery in patients receiving allogeneic blood cell transplantation (BCT) with those receiving allogeneic bone marrow transplantation (BMT). PATIENTS AND METHODS: One hundred eleven patients with leukemia in the early stages and with HLA-matched sibling donors were randomized in this study. One hundred one underwent transplantation. Standard procedures for collection and transplantation were used. Patients did not receive prophylactic granulocyte colony-stimulating factor after undergoing transplantation. In addition to clinical end points being established, a prospective and comparative economic evaluation of the first 6 months after transplantation was performed. RESULTS: Groups were balanced for patient, donor, and transplant characteristics. Blood cell collection led to the collection of a higher number of CD34(+) and CD3(+) cells than did bone marrow collection (P < 10(-6)) without reported side effects for the donor. Patients in the BCT group reached platelet counts of 25 and 50 x 10(9) platelets/L 8 and 11 days earlier than did the BMT group (P < 10(-4) and P < 10(-5)), respectively. This resulted in fewer platelet transfusions during the first 180 days after transplantation (P =.002) for the former group. The time to reach neutrophil counts of 0.5 and 1 x 10(9) neutrophils/L was 6 and 7 days shorter, respectively, in the BCT group than in the BMT group (P < 10(-5)). This quicker hematologic recovery was associated with a shorter length of hospitalization and a decrease in total cost of procedure during the first 6 months. CONCLUSION: This study establishes that allogeneic BCT results in quicker hematologic recovery but is associated with a higher occurrence of chronic graft-versus-host disease.

Optimization of peripheral blood stem cell collection by leukopheresis. Interaction between economic and clinical assessment of an innovation.

Using the example of substitution of peripheral blood stem cell (PBSC) collection to bone marrow harvest for autologous transplantation in cancer patients, our study attempts to illustrate how economic assessment, starting at an early stage of medical innovation, can influence the development and diffusion process of a new technological procedure whose optimal design has not yet been established. Two cost minimization studies comparing costs for obtaining a clinically reinfusable graft using bone marrow harvest or alternatively various protocols of PBSC collection contributed to a change in the French clinical standard for this procedure.

Psychosocial aspects of haematopoietic stem cell donation for allogeneic transplantation: how family donors cope with this experience.

Peripheral blood stem cell (PBSC) allogeneic transplantation is an innovative medical procedure which has many advantages in comparison with bone marrow (BM) transplantation, but it involves administering haematopoietic growth factors (HGFs) to donors, the long-term physiological effects of which have not yet been established. The main aim of the present study was to analyse how family PBSC donors cope when confronted with this particular risk context. In addition to data collected on the personal and social aspects of the donors' experience, questionnaires were used to measure their quality of life (pain and anxiety) before, during and after donation, and they were subsequently interviewed in depth by a psychologist. Twenty-two donors participated in this study. They did not all react to the experience of blood cell donation in the same way, in terms of their own personal feelings, attitudes towards the donation, their relationships with the other members of the family, and their awareness of the risk involved.

Clinical and economic comparison of lenograstim-primed blood cells (BC) and bone marrow (BM) allogeneic transplantation.

The study presented is a clinical and economic comparison of bone marrow (BM) and blood cells (BC) allogeneic transplantation. We performed a case-control study to compare 17 patients receiving allogeneic BC transplant in a pilot study to an historical group of 17 patients allografted with BM. We evaluated the clinical outcomes and the direct medical costs of transplantation from conditioning regimen until day 100 by detailed observation of patients' medical records. Patients in the BC group received a median of 8 x 10(6)/kg CD34+ cells (1.58-29.1) and 266 x 10(6)/kg CD3+ cells (128-469). All patients had neutrophil engraftment with a median of 14 days in the BC group vs 19 days in the BM group (P < 0.05). The Kaplan-Meier estimation of the median number of days to a platelet count of > 25 x 10(9)/l, independent of platelet transfusion, was significantly shorter in the BC group (15 (9-74)) compared with the BM group (25 (15-45)). Acute graft-versus-host disease (AGVHD) of grade > or = 2 was not significantly different between the two groups. Patients treated with BC presented a US$16,134 decrease in the cost of the first 100 days (29%, P = 0.006). Our comparison suggested that platelet reconstitution and total costs were in favor of the BC group.

Autologous peripheral blood progenitor-cell transplantation versus autologous bone marrow transplantation for adults and children with non-leukaemic malignant disease. A randomised economic study.

A prospective economic analysis of autologous peripheral blood progenitor-cell transplantation (PBPCT) versus autologous bone marrow transplantation (BMT) was performed as part of a randomised clinical trial in 129 patient (adults and children) receiving high-dosage antineoplastic therapy for non-leukaemic malignant disease. The clinical assessment criteria of the study were the duration of thrombocytopenia (< 30 x 10(9)/L and < 50 x 10(9)/L) and of granulocytopenia (< 0.5 x 10(9)/L). The cost of medical resources used was the primary economic end-point. We also calculated the cost of reaching 2 specified haematological end-points: platelet recovery (> or = 30 x 10(9)/L) and granulocyte recovery (> or = 0.5 x 10(9)/L). Economic analysis was based on the French hospital perspective. Haematological recovery was significantly quicker in the PBPCT groups (adults and children) compared with the BMT groups. Economic study revealed that the PBPCT groups were clearly less expensive with regard to costs up to discharge (17% decrease of the average cost for adults and 29% for children) and those associated with specified haematological end-points. The global costs of PBPCT were lower than those of BMT for these adult and paediatric populations. Economic arguments can clearly be added to clinical ones in favour of substitution of autologous PBPCT for autologous BMT. International comparisons of diffusion of PBPCT could be of great interest for further economic research into medical innovation.
