In the French national health insurance information system (SNIIR-AM), routine records of health claimed reimbursements are linked to hospital admissions for the whole French population. The main focus of this work is the usability of this system for vaccine safety assessment programme. Self-controlled case series analyses were performed using an exhaustive SNIIR-AM extraction of French children aged less than 3 years, to investigate the relationship between MMR immunization and children hospitalizations for febrile convulsions, a well-documented rare adverse event, over 2009-2010. The results suggest a significant increase of febrile convulsions during the 6-11 days period following any MMR immunization (IRR = 1.49, 95% CI = 1.22, 1.83; p= 0.0001) and no increase 15-35 days post any MMR immunization (IRR = 1.03, 95% CI = 0.89, 1.18; p= 0.72). These results are in accordance with other results obtained from large epidemiologic studies, which suggest the usability of the SNIIR-AM as a relevant database to study the occurrence of adverse events associated with immunization. For future use, results associated with risk of convulsion during the day of vaccination should nevertheless be considered with particular caution. © 2013 Elsevier Ltd. Source

Introduction: An increased incidence of asthma has been reported among healthcare workers. The role of quaternary ammonium compounds (QACs), commonly used in cleaning/disinfection products, has not been clearly defined. The aim of this study was to analyse associations between asthma and occupational exposure to disinfectants, especially QACs. Methods: The study was performed on a stratified random sample of the various healthcare departments of 7 healthcare settings. The study included: questionnaire, physical examination and specific IgE assays. Occupational exposure assessment was performed by means of a work questionnaire, workplace studies and a review of products ingredients. Data were analysed by logistic regression. Results: Response rate was 77%; 543 workers (89% female) participated; 37.1% were registered nurses (RNs), 16.4% auxiliary nurses (ANs), 17.3% cleaners; 32.8% were atopic. 335 participants were exposed to QACs. Nursing professionals reported a significantly higher risk of reported physician-diagnosed asthma and, for RNs, of nasal symptoms at work than administrative staff working in healthcare sector. This risk was particularly marked during disinfection tasks and when exposure to QACs. Exposure to QACs increased significantly the risk of reported physician-diagnosed asthma and nasal symptoms at work (adjusted OR = 7.5 and 3.2, respectively). No significant association was found with other exposures such as latex glove use, chlorinated products/bleach or glutaraldehyde. Conclusion: RNs and ANs presented a higher risk of reported asthma than administrative staff. The highest risk was associated with tasks involving dilution of disinfection products by manual mixing, suggesting possible exposure to repeated peaks of concentrated products known to be strong respiratory irritants. Workplace interventions should be conducted to more clearly determine QAC exposure and improve disinfection procedures. © 2013 John Wiley & Sons Ltd. Source

Background: Triple negative breast cancer (TNBC) is a heterogeneous group of tumors for some of which the Epithelial Growth Factor Receptor (EGFR) pathway may play an important role. We investigated the efficacy and toxicity of an anti-EGFR antibody (panitumumab) combined with a standard neoadjuvant anthracycline-taxane based chemotherapy in patients with operable, stage II-III, TNBC. Methods: Treatment in this multicentric neoadjuvant pilot study consisted of panitumumab (9 mg/kg) for 8 cycles q.3 weeks combined with 4 cycles of 5-fluorouracil, epidoxorubicin and cyclophosphamide (FEC100: 500/100/500 mg/m2) q.3 weeks followed by 4 cycles of docetaxel (T: 100 mg/m2) q.3 weeks. Following therapy, all patients underwent surgical resection. Pathological complete response (pCR) in evaluable patients was the main endpoint while clinical response, toxicity and ancillary studies were secondary endpoints. Paraffinembedded and frozen tumor samples were systematically collected with the aim to identify predictive biomarkers of efficacy and resistance in order to select biologically defined subpopulations for potential further clinical development of the anti-EGFR antibody. Results: Sixty patients were enrolled with 47 assessable for pathologic response. The pathological complete response (pCR) rates were 46.8% [95% CI: 32.5-61.1] and 55.3% [95% CI: 41.1-69.5] according respectively to Chevallier and Sataloff classifications. The complete clinical response rate (cCR) was 37.5%. Conservative surgery was performed in 87% of cases. Toxicity was manageable. The association of high EGFR and low cytokeratin 8/18 expression in tumor cells on one hand and high density of CD8+ tumor-infiltrating lymphocytes on the other hand were significantly predictive of pCR. Conclusions: Panitumumab in combination with FEC100 followed by docetaxel appears efficacious, with acceptable toxicity, as neoadjuvant therapy of operable TNBC. Several biomarkers could help define large subsets of patients with high probability of pCR, suggesting a potential interest to further develop this combination in biologically defined subgroups of patients with TNBC. © The Author 2014.

Background. The number of long-term colorectal cancer survivors is increasing. Cancer and its treatment can cause physical and psychological complications, but little is known about how it impacts quality of life (QOL) over the long term-5, 10, and 15 years after diagnosis. Methods. Cancer survivors were randomly selected from three tumor registries in France, diagnosed in 1990 (±1 year), 1995 (±1 year), and 2000 (±1 year). Controls were randomly selected from electoral rolls, stratifying on gender, age group, and residence area. Participants completed two QOL questionnaires, a fatigue questionnaire, an anxiety questionnaire, and a life conditions questionnaire. An analysis of variance was used to compare QOL scores of cancer survivors by period of diagnosis (5, 10, and 15 years) with those of controls, adjusted for sociodemographic data and comorbidities. Results. We included 344 colon cancer and 198 rectal cancer survivors and 1,181 controls. In a global analysis, survivors reported a statistically and clinically significant lower score in social functioning 5 years after diagnosis and higher scores in diarrhea symptoms 5 and 10 years after diagnosis. In subgroup analyses, rectal cancer affected QOL in the physical dimensions at 5 years and in the fatigue dimensions at 5 and 10 years. Conclusion. Survivors of colorectal cancer may experience the effects of cancer and its treatment up to 10 years after diagnosis, particularly for rectal cancer. Clinicians, psychologists, and social workers must pay special attention to rectal cancer survivors to improve overall management. © AlphaMed Press. Source

Purpose: To characterize response shift effects in patients with breast cancer (BC). Methods: The QLQ-C30, BR23, and EurQOL-EQ-5D were assessed at baseline and at the end of the first hospitalization. We used the then-test approach to characterize changes in internal standards by calculating the mean difference between the then-test (retrospective measure) and pre-test baseline QoL assessments. The Ideal Scale Approach was also used to assess changes in standards by comparing health and QoL expectancies between baseline and the end of the first hospitalization. Successive Comparison Approach was used to assess changes in values through the longitudinal assessment of the relative importance of EuroQOL dimensions. Results: The results of this study showed that recalibration RS effects occurred early after the first hospitalization for 6/15 dimensions of QLQ-C30 (emotional, cognitive, fatigue, insomnia, appetite loss, diarrhea) and 2/8 of BR-23 (future perspective, systemic therapy side effects). Moreover, health and QoL expectancies changed between the baseline and the end of the first hospitalization, and changes in values were seen for the self-care and usual activities dimensions of the EuroQOL-EQ-5D. Conclusions: The occurrence of RS early after the first hospitalization suggests that it needs to be taken into account to interpret QoL changes in BC. © 2012 Springer Science+Business Media B.V.
