We aim to determine whether differences in survival exist between two populations of women with metastatic breast cancer (MBC) and to identify prognostic factors of survival after metastasis diagnosis. Data on women with MBC diagnosed between 2000 and 2011 were provided by the Côte d'Or Breast cancer registry. Survival rates and median overall survival (OS) after metastasis diagnosis were determined using the Kaplan–Meier method and prognostic factors were determined in a Cox proportional hazard model. Overall, 282 women with primary MBC and 340 with secondary MBC were included. A 2‐year survival rate was significantly better in women with primary MBC (50.8% [95% CI: 47.8–53.8%] versus 44.5% [95% CI: 41.8–47.2%]). However, median OS did not differ between the two groups (p = 0.1). The prognostic factors associated with worst survival were a triple‐negative tumor type (p < 10?4), multiple metastases sites (p < 10?4), an older age at metastasis (p < 10?4), and a SBR grade G3 (p = 0.007). OS between women with primary MBC and women with secondary MBC does not seem to differ significantly. This population‐based study provides original epidemiological data on French women without any selection bias inherent to hospital cohorts. 相似文献

Early March 2019, health authorities of Matadi in the Democratic Republic of the Congo alerted a sudden increase in acute fever/arthralgia cases, prompting an outbreak investigation. We collected surveillance data, clinical data, and laboratory specimens from clinical suspects (for CHIKV-PCR/ELISA, malaria RDT), semi-structured interviews with patients/caregivers about perceptions and health seeking behavior, and mosquito sampling (adult/larvae) for CHIKV-PCR and estimation of infestation levels. The investigations confirmed a large CHIKV outbreak that lasted February–June 2019. The total caseload remained unknown due to a lack of systematic surveillance, but one of the two health zones of Matadi notified 2686 suspects. Of the clinical suspects we investigated (n = 220), 83.2% were CHIKV-PCR or IgM positive (acute infection). One patient had an isolated IgG-positive result (while PCR/IgM negative), suggestive of past infection. In total, 15% had acute CHIKV and malaria. Most adult mosquitoes and larvae (>95%) were Aedes albopictus. High infestation levels were noted. CHIKV was detected in 6/11 adult mosquito pools, and in 2/15 of the larvae pools. This latter and the fact that 2/6 of the CHIKV-positive adult pools contained only males suggests transovarial transmission. Interviews revealed that healthcare seeking shifted quickly toward the informal sector and self-medication. Caregivers reported difficulties to differentiate CHIKV, malaria, and other infectious diseases resulting in polypharmacy and high out-of-pocket expenditure. We confirmed a first major CHIKV outbreak in Matadi, with main vector Aedes albopictus. The health sector was ill-prepared for the information, surveillance, and treatment needs for such an explosive outbreak in a CHIKV-naïve population. Better surveillance systems (national level/sentinel sites) and point-of-care diagnostics for arboviruses are needed. 相似文献

Major sickle cell disease syndrome (SCD) is a set of potentially serious and disabling constitutional haemoglobin pathologies characterised by chronic haemolysis and vaso‐occlusion phenomena. If expression takes the form of acute vaso‐occlusive crisis, SCD is currently considered to be a chronic systemic pathology, primarily associated with vasculopathy and ischaemia‐reperfusion phenomena. The haemolytic aspect of the disease may be associated with endothelial dysfunctional complications, including leg ulcers, which are a classic spontaneous complication of major SCD. Their frequency, all aetiologies combined, varies considerably according to the series under consideration. Hydroxycarbamide has become the standard treatment for some SCD phenotypes, but has classically been described as one of the causes of leg ulcer. This causality is widely debated and is still difficult to establish because it is a specific complication of the disease. Comorbidity factors (eg, iron deficiency) are also often implicated as causal or aggravating factors so research into all the potential aetiologies of leg ulcers in a sickle cell patient must be exhaustive. We discuss the aetiologies of a leg ulcer in a patient treated by hydrocarbamide for major SCD. The imputation of the drug was established, followed by a marrow allograft in this patient. 相似文献
