Backgroundpostnatal depression (PND) is a major public health problem. The objective of this study was to improve early PND screening by midwives in a maternity unit. Professional screening techniques were evaluated and compared with reference screening techniques [Edinburgh Postnatal Depression Scale (EPDS), Mini International Neuropsychiatric Interview (MINI-DSM-IV)].Methodsthe evaluation took place before and after the midwife training in order to determine the effectiveness of specific clinical recommendations for two successive 10-week inclusion periods (from November 2004 to September 2005). A short training course and posters were used to convey the recommendations, agreed by obstetricians, paediatricians and psychiatrists.Resultsa total of 463 postpartum women were included in the two phases of the study. Quantitative and qualitative PND screening by midwives improved significantly following training (Z=2.07, p=0.04; Z=2.62, p=0.008, respectively). Early detection of major depressive episodes increased by 37.7% (95% confidence interval 25.7–49.7) following training. A combination of midwives’ perception of poor emotional well-being and the EPDS led to a significant improvement in early detection of PND (Q=8.00, p=0.04).Discussiontargeted recommendations given to the midwives led to an improvement in the early detection of PND. Suitable programmes need to be offered to reduce the number of cases of PND. Perinatal psychiatrists should be seen to be meticulous and available for such prevention action. 相似文献

This review presents the rationale for and main results of coagulation inhibitor substitution during experimental and human sepsis. Activation of the contact system induces activation of the classical complement pathway with generation of anaphylatoxins, of the kinins pathway and of fibrinolysis. Physiologic inhibition depends on the C1-inhibitor (C1-Inh.). Septic patients exhibit a relative deficiency of biologically active C1-Inh. Substitution with concentrations of C1-Inh has been safely performed and preliminary results are consistent with a possible beneficial effect on hypotension and vasopressor requirement in septic shock. The extrinsic pathway is the main initial coagulation process involved in sepsis-induced DIC. Endothelial and monocyte generation of tissue factor (TF) is activated by bacterial products and endotoxin. Activation of TF is counteracted by a specific tissue factor pathway inhibitor (TFPI). The potential for TFPI substitution to inhibit the activation of the coagulation cascade in sepsis requires further study. Thrombin generation is inhibited by antithrombin III (AT III) and the protein C-protein S system. During sepsis, AT III is consumed and degraded by elastase. Animal studies have shown that DIC and death were prevented by high doses of AT III concentrates. Although a significant reduction in the duration of biological symptoms of DIC has been reported in most human studies, the usefulness of AT III substitution in human sepsis is still debated. None of the studies was able to document a statistically significant reduction in mortality. Protein C is activated by thrombomodulin and, with its cofactor protein S, inhibits factors V a and VIII a. The free level of protein S depends on the level of the C4b binding protein (C4 bBP), an acute-phase complement regulatory protein. During sepsis, protein C activity is significantly reduced, either by acute consumption or by thrombomodulin down-regulation, and increased levels of plasma C4 bBP inhibit protein S. Infusion of activated protein C and protein S substitution both protect animals from the lethal effects of bacteria. Combining these different coagulation inhibitors should be carefully studied before its use in septic patients is recommended. 相似文献

Reevaluation of the prognostic factors for splenectomy in chronic idiopathic thrombocytopenic purpura (ITP): a report on 181 cases 总被引:3,自引:0,他引:3

From 1973 to 1986 we splenectomized 181 patients with chronic ITP after platelet kinetic studies with 51Cr or 111In. Mean age at diagnosis was 34 (range 4-79 yr). Follow-up of at least 1 yr after splenectomy was available in every patient. 141 patients (78%) achieved remission (platelets greater than 100 x 10(9)/l by 3 months after splenectomy), of whom 9 subsequently relapsed. Among the 40 non-responders at 3 months, 3 achieved a later remission spontaneously. Factors associated with response to splenectomy included a high post-operative platelet count (p = 0.0001), younger age at the time of surgery (p = 0.0077) and predominantly splenic sequestration of platelets (p = 0.0002), the two latter factors being partially correlated. In a multivariate analysis, however, only post-operative platelet count and age retained an independent prognostic significance, whereas the sequestration site of platelets had only borderline value. These results are discussed in the context of indications of platelet kinetic studies in chronic ITP, before splenectomy is considered. 相似文献

We report 2 new mutations identified in 3 patients and characterized by the markedly decreased affinity of von Willebrand factor (vWF) for factor VIII (FVIII). Patients 2 and 3, who have a typical type 2N phenotype, were found to be compound heterozygous for Arg91Gln and Cys25Tyr or Cys95Phe, respectively. Patient 1, who is the first cousin of patient 2, had an FVIII binding defect of vWF, low levels of vWF, and multimeric impairment. She was found to be compound heterozygous for the mutations Cys25Tyr and a stop codon (D93ter) in exon 4. Transient expression of recombinant vWF (rvWF) containing either Cys25Tyr or Cys95Phe mutations resulted in mutated rvWF with markedly reduced FVIII binding ability, multimeric structure impairment, and a significant decrease in the vWF expression level. Moreover, the use of anti-vWF monoclonal antibodies that inhibit the FVIII binding showed that these 2 mutations likely induce a conformational change in the D' domain. These results show that the native conformation of the D' domain of vWF is not only required for FVIII binding but also for normal multimerization and optimal secretion. 相似文献

BACKGROUND AND OBJECTIVES: Information about the long-term efficacy of interferon alpha (interferon-alpha) in haemophilic patients with chronic hepatitis not co-infected with the human immunodeficiency virus (HIV-1) is still limited. Previous studies seemed to indicate a low rate of response. The aim of this study was to evaluate the safety and long-term efficacy of interferon treatment in multi-transfused haemophiliacs. METHODS: Fifty-eight haemophiliacs were scheduled to receive 3 MU of interferon-alpha 2b three times a week for 12 months. The patients were followed up for at least 24 months post-treatment. Response was assessed by measurements of serum hepatitis C virus (HCV) RNA. RESULTS: Twenty-four patients (41.4%) dropped out. Except for seven patients, the symptoms that led to interrupting interferon treatment would probably not have resulted in the same decision in non-haemophilic patients. One patient developed an inhibitor to the deficient clotting factor without haemorrhagic consequences. In an intent to treat, the sustained virological response rate was 14%. However, when considering only the 34 patients who received the full treatment, HCV-RNA was cleared in eight patients (23%). CONCLUSIONS: This study suggests that multi-transfused haemophiliacs with chronic hepatitis not co-infected with HIV-1 respond to prolonged treatment with interferon-alpha in a similar proportion to that observed in non-haemophiliacs. There was a high rate of patients who did not complete the interferon-alpha treatment, and this seems to be characteristic of this patient population. 相似文献

In vitro and in vivo Evaluation of a Factor VIII Concentrate Heat-Treated to Inactivate HTLV-III/LAV Viruses 总被引:1,自引:0,他引:1

We report here the results of our evaluation of the effects of a dry heat treatment (96 h at 68 degrees C) to eliminate LAV/HTLV-III virus on factor VIII (FVIII) and von Willebrand factor (vWf) present in an intermediate-purity concentrate. This thermal inactivation appears to have little effect on FVIII. There is an acceptable loss (12.3 +/- 3.6%; n = 25) in FVIII coagulant activity (FVIII: C) and a good in vivo performance in haemophilia A patients. A precise analysis of vWf indicates that whereas the vWf antigen and its ristocetin cofactor activity decrease during heating, there is an increase in potentially functional forms of vWf. Heat treatment induces an increase in high molecular weight forms of vWf and an enhancement in platelet adhesion to collagen. These changes probably explain the correcting effect on the bleeding time of the heated FVIII concentrate in patients with von Willebrand's disease. Thus, this heat-treated concentrate appears to be equivalent to the untreated product in haemophilia A, with the additional benefit of being efficient for the treatment of von Willebrand's disease. 相似文献

We have performed a biochemical mapping of the neurofibrillary degeneration in all cortical areas of Alzheimer patients, using the immunological quantification of pathological tau 55, 64, and 69. These abnormally phosphorylated proteins, which are the basic components of PHF, are reliable markers of the degenerating process in Alzheimer disease. Here, we report our biochemical findings on a brain from a 90-yr-old woman with an 8-yr history of Alzheimer disease who exhibited dramatic and general cortical involvement. The detection of these markers was very high in all Brodmann areas, even in primary motor, somatosensory, or visual cortex. This case report contrasts with other studies, which suggested that a more virulent disease process is generally associated with an early onset and argues for the heterogeneity of the disease. Moreover, we show here that the immunodetection of abnormal tau proteins using the western blot method is a precise, reliable, and reproducible way to quantify the degenerating process in AD. 相似文献

Summary. The systematic study of 160 multitransfused patients immunization has permitted the detection of two precipitating antilipoprotein antibodies, one of them in a patient suffering from haemophilia, the other one in a child with congenital anaemia. The specificity of the first antibody is not determined. The second one is an anti Ag (x) antibody. 相似文献
