Methicillin-susceptible Staphylococcus aureus isolates, recovered from 204 patients in our hospital in a 22-month period, were characterized by pulsed-field gel electrophoresis. Among the multiple S. aureus types six clonal lineages dominated, comprising isolates from 158 patients. Despite the limited genetic variation, cross-transmission was made plausible only sporadically. 相似文献

Chronic cannabis use can be associated with uncontrollable vomiting and abdominal pain. Diagnostic criteria for cannabinoid hyperemesis syndrome (CHS) were defined in 2012 by Simonetto et al. The objectives of this study were to describe the prevalence of CHS, the patients' epidemiological characteristics, and to show the difficulties encountered in caring for these patients in emergency departments, the extent of health care and an unsuitable follow‐up in general practices. A prospective cohort of patients with CHS was recruited among a target population of patients leaving the adult emergency services of the Marseille hospitals Nord and La Timone between October 2017 and July 2018, with abdominal pain syndrome of unidentified etiology. Inclusion criteria for the CHS cohort were chronic cannabis use associated with nausea and vomiting. There were 48 patients included in the CHS cohort who took cannabis daily, in a target population of 2 848 patients (i.e. 1.6%). A hot shower was the most effective symptomatic treatment in 54.2% of cases. Patients suffering from CHS spent significantly more hours in emergency departments (11 vs. 6.5), and, on average, visits were more frequent (4.9 vs. 3). 20.3% of them were hospitalized to continue pain medication. Once out of hospital, follow‐up was limited, and weaning off cannabis, the only etiological treatment, was difficult to set up. Informing patients about CHS is essential, and a hot shower could be systematically proposed, thus limiting an unnecessary extent of health care. CHS is genuine, medical staff should be made aware of it in occupational training, and it should be seriously considered in health policies. 相似文献

Summary
The coagulation system does not only offer protection against bleeding, but also aids in our defense against invading microorganisms. The hemostatic system and innate immunity are strongly entangled, which explains why so many infections are complicated by either bleeding or thrombosis. Staphylococcus aureus (S. aureus), currently the most deadly infectious agent in the developed world, causes devastating intravascular infections such as sepsis and infective endocarditis. During these infections S. aureus comes in close contact with the host hemostatic system and proves to be a master in manipulating coagulation. The coagulases of S. aureus directly induce coagulation by activating prothrombin. S. aureus also manipulates fibrinolysis by triggering plasminogen activation via staphylokinase. Furthermore, S. aureus binds and activates platelets and interacts with key coagulation proteins such as fibrin(ogen), fibronectin and von Willebrand factor. By manipulating the coagulation system S. aureus gains a significant advantage over the host defense mechanisms. Studying the interplay between S. aureus and the hemostatic system can therefore lead to new innovative therapies for battling S. aureus infections.5.

Background
Both activated Thrombin Activatable Fibrinolysis Inhibitor (TAFI) and active Plasminogen Activator Inhibitor-1 (PAI-1) attenuate fibrinolysis and may therefore contribute to the pathophysiology of Venous ThromboEmbolism (VTE). Whether increased TAFI and/or PAI-1 concentrations are associated with VTE is unclear.Objective
To study an association of impaired fibrinolysis and VTE using a comprehensive panel of in-house developed assays measuring intact TAFI, activation peptide of TAFI (AP-TAFI), PAI-1 antigen, endogenous PAI-1:t-PA complex (PAI-1:t-PA) and active PAI-1 levels in 102 VTE patients and in 113 healthy controls (HC).Results
Active PAI-1 was significantly higher in VTE patients compared to HC (20.9 [9.6-37.8] ng/ml vs. 6.2 [3.5-9.7] ng/ml, respectively). Active PAI-1 was the best discriminator with an area under the ROC curve and 95% confidence interval (AUROC [95%CI]) of 0.84 [0.79-0.90] compared to 0.75 [0.68-0.72] for PAI-1:t-PA, 0.65 [0.58-0.73] for PAI-1 antigen, 0.62 [0.54-0.69] for AP-TAFI and 0.51 [0.44-0.59] for intact TAFI. Using ROC analysis, we defined an optimal cut-off of 12.8 ng/ml for active PAI-1, with corresponding sensitivity of 71 [61–79] % and specificity of 89 [82–94] %. A lack of association with the time between VTE event and sample collection or with the intake of anticoagulant treatment suggests that active PAI-1 levels are sustainable high in VTE patients.Conclusions
This case–control study emphasizes the clinical importance of measuring active PAI-1 instead of PAI-1 antigen and identifies active PAI-1 as a potential marker of VTE. Prognostic studies will need to address the clinical significance of active PAI-1 as biomarker. 相似文献8.

Stroke is the most common cardiovascular disorder after heart disease, with a high mortality and often poor quality of life in survivors. Atrial fibrillation (AF), the most commonly occurring sustained cardiac arrhythmia increases the risk of stroke by five. However, stroke risk is not homogeneous and varies with associated morbidities and risk factors. Risk assessment scores have been developed and according to the calculated level of risk, guidelines recommend treatment with antithrombotic agents, preferably vitamin K antagonists (VKA). Despite these recommendations many patients with AF do not receive adequate thromboprophylaxis. The presence of AF is often not recognized and VKA are underused due to doctor- or patient-related factors and intrinsic disadvantages of these drugs. An awareness campaign for the diagnosis of AF is warranted, highlighting the risk of stroke. Novel anticoagulants that largely overcome many of the limitations of vitamin K antagonists are becoming available. 相似文献

Objectives: The aim of the study was to assess the prevalence of oral contraceptive (OC) use, user characteristics and prescribing patterns by accessing health care databases of three European countries.Methods: A retrospective study was performed from 2009 to 2010 in three general practice (GP) databases from the Netherlands, UK and Italy and in one database of linked pharmacy and hospitalisation data in the Netherlands. The presence of selected chronic conditions and diagnoses of diseases associated with OC use were assessed, as were switches, discontinuations and types of OC used during the study period.Results: Among 2.16 million women aged 15 to 49 years, 16.0% were using an OC on 1 January 2010. The prevalence ranged from 19.7% in a Dutch database to 2.6% in the Italian database. During 2009 and 2010, mainly second-generation progestogens were prescribed in the Netherlands (79.4% and 78.3% of users), both second- (57.9%) and third-generation progestogens (43.6%) were prescribed in the UK, and mainly third-generation progestogens in Italy (61.8%). Most switches were to third- or fourth-generation pills. The prevalence of chronic diseases tended to be higher among OC users, and the proportions of women with a history of disease associated with OC use tended to be lower than among non-users.Conclusions: Second-generation OCs were most frequently prescribed in the Netherlands. In the UK, and even more so in Italy, many women used third- or fourth-generation OCs. Preparation switches were mainly to third- or fourth-generation OCs. Among OC users, a somewhat higher prevalence of chronic diseases was observed; however, information bias cannot be ruled out. 相似文献
