Objectives: We examined the characteristics and outcomes of patients requiring valve surgery during active infective endocarditis (IE), focusing on the impact of antimicrobial therapy. Methods: In this retrospective study, medical charts of all consecutive patients admitted to our cardiovascular surgery department from January 1998 to December 2010, with a diagnosis of IE requiring surgical management, were reviewed. Adult patients were enrolled in the study if they had definite or possible active IE and if the antimicrobial treatment was evaluable. Results: After initial screening of medical records, we selected 173 surgically treated patients (135 men; mean age, 55.8 years). Native valves were involved in 150 (87%) patients. IE mainly involved the aortic valve (n = 113) and then mitral (n = 83), tricuspid (n = 13), and pulmonary (n = 3) valves. The most common causative pathogens were streptococci (n = 70), staphylococci (n = 60), and enterococci (n = 29). Operative mortality was 15%. Multivariate logistic regression analysis demonstrated that adequacy of the overall antimicrobial treatment (adjusted odds ratio, 0.292; 95% confidence interval, 0.117-0.726; P =.008) and temperature greater than 38 C at the time of diagnosis (adjusted odds ratio, 0.288; 95% confidence interval, 0.115-0.724; P =.008) were independently associated with a lower risk of mortality. Conversely, age greater than 60 years (adjusted odds ratio, 4.42; 95% confidence interval, 1.57-12.4; P =.005) was associated with a greater risk of operative mortality. Conclusions: Surgery for active IE is still associated with a high mortality rate, but its prognosis is significantly improved by adequate antimicrobial therapy.

Human Mutation | Year: 2014
Stormorken syndrome is a rare autosomal-dominant disease with mild bleeding tendency, thrombocytopathy, thrombocytopenia, mild anemia, asplenia, tubular aggregate myopathy, miosis, headache, and ichthyosis. A heterozygous missense mutation in STIM1 exon 7 (c.910C>T; p.Arg304Trp) (NM_003156.3) was found to segregate with the disease in six Stormorken syndrome patients in four families. Upon sensing Ca2+ depletion in the endoplasmic reticulum lumen, STIM1 undergoes a conformational change enabling it to interact with and open ORAI1, a Ca2+ release-activated Ca2+ channel located in the plasma membrane. The STIM1 mutation found in Stormorken syndrome patients is located in the coiled-coil 1 domain, which might play a role in keeping STIM1 inactive. In agreement with a possible gain-of-function mutation in STIM1, blood platelets from patients were in a preactivated state with high exposure of aminophospholipids on the outer surface of the plasma membrane. Resting Ca2+ levels were elevated in platelets from the patients compared with controls, and store-operated Ca2+ entry was markedly attenuated, further supporting constitutive activity of STIM1 and ORAI1. Thus, our data are compatible with a near-maximal activation of STIM1 in Stormorken syndrome patients. We conclude that the heterozygous mutation c.910C>T causes the complex phenotype that defines this syndrome. © 2014 WILEY PERIODICALS, INC.

Objectives: To analyse published cost-of-illness studies that had assessed the cost of prematurity according to gestational age at birth. Methods: A review of the literature was carried out in March 2011 using the following databases: Medline, ScienceDirect, The Cochrane Library, Econlit and Business Source Premier, and a French Public-Health database. Key-word sequences related to 'prematurity' and 'costs' were considered. Studies that assessed costs according to the gestational age (GA) at the premature birth (<37 weeks of gestation) in industrialized countries and during the last two decades were included. Variations in the reported costs were analysed using a check-list, which allowed the studies to be described according to several methodological and contextual criteria. Results: A total of 18 studies published since 1990 were included. According to these studies, costs were assessed for different follow-up periods (short, medium or long-term), and for different degrees of prematurity (extreme, early, moderate and late). Results showed that whatever the follow-up period, costs correlated inversely with GA. They also showed considerable variability in costs within the same GA group. Differences between studies could be explained by the choices made, concerning i/the study populations, ii/contextual information, iii/and various economic criteria. Despite these variations, a global trend of costs was estimated in the short-term period using mean costs from four American studies that presented similar methodologies. Costs stand at over US$ 100,000 for extreme prematurity, between US$ 40,000 and US$ 100,000 for early prematurity, between US$ 10,000 and US$ 30,000 for moderate prematurity and below US$ 4500 for late prematurity. Conclusion: This review underlined not only the clear inverse relationship between costs and GA at birth, but also the difficulty to transfer the results to the French context. It suggests that studies specific to the French health system need to be carried out. © 2013 The Royal Society for Public Health.

Purpose: The purpose of our multidisciplinary study was to define a pragmatic and secure alternative to the creation of a national centralised medical record which could gather together the different parts of the medical record of a patient scattered in the different hospitals where he was hospitalised without any risk of breaching confidentiality. Methods: We first analyse the reasons for the failure and the dangers of centralisation (i.e. difficulty to define a European patients' identifier, to reach a common standard for the contents of the medical record, for data protection) and then propose an alternative that uses the existing available data on the basis that setting up a safe though imperfect system could be better than continuing a quest for a mythical perfect information system that we have still not found after a search that has lasted two decades. Results: We describe the functioning of Medical Record Search Engines (MRSEs), using pseudonymisation of patients' identity. The MRSE will be able to retrieve and to provide upon an MD's request all the available information concerning a patient who has been hospitalised in different hospitals without ever having access to the patient's identity. The drawback of this system is that the medical practitioner then has to read all of the information and to create his own synthesis and eventually to reject extra data. Conclusions: Faced with the difficulties and the risks of setting up a centralised medical record system, a system that gathers all of the available information concerning a patient could be of great interest. This low-cost pragmatic alternative which could be developed quickly should be taken into consideration by health authorities. © 2010 Elsevier Ireland Ltd.

Background: Ziconotide is a new analgesic agent administered intrathecally. It is challenging to use and can induce several and sometimes serious adverse events. A low initial dosage followed by slow titration may reduce serious adverse events. Objective: To determine whether a low starting dosage of ziconotide, followed by slow titration, decreases the incidence of major adverse events associated with ziconotide when used for intractable cancer pain Study Design: Observational cohort study. Setting: Three French cancer centers Methods: Patients with incurable cancer causing chronic pain rated above 6/10 on a numerical scale while receiving high-dose opioid therapy (more than 200 mg/d of oral morphine equivalent) and/or exhibiting severe opioid-related adverse events received intrathecal infusions of ziconotide combined with morphine, ropivacaine, and clonidine. Results: Seventy-seven patients were included. Adverse events were recorded in 57% of them; moderate adverse events occurred in 51%. Adverse events required treatment discontinuation in 7 (9%) including 5 (6%) for whom a causal role for ziconotide was highly likely; among them 4 (5%) were serious. All patients experienced a significant and lasting decrease in pain intensity (by 48%) in response to intrathecal analgesic therapy that included ziconotide Limitations: Limitations include the nonrandomized, observational nature of the study. Determining the relative contributions of each drug to adverse events was difficult, and some of the adverse events manifested as clinical symptoms of a subjective nature. Conclusions: The rates of minor and moderate adverse events were consistent with previous reports. However, the rate of serious adverse events was substantially lower. Our study confirms the efficacy of intrathecal analgesia with ziconotide for relieving refractory cancer pain. These results indicate that multimodal intrathecal analgesia in patients with cancer pain should include ziconotide from the outset in order to provide time for subsequent slow titration.

Background: Mortality associated with aortic graft infection is considerable. The gold standard for surgical treatment remains explantation of the graft. However, prognostic factors associated with early mortality due to this surgical procedure are not well-known.Methods: Retrospective analysis of patients admitted in our center between January 2006 and October 2011 for aortic graft infection. The primary endpoint was in-hospital mortality. A bivariate analysis of characteristics of patients associated with in-hospital outcome was performed.Results: Twenty five evaluable patients were studied. All patients were male. Their mean age was 67 ± 8.4 years. Most of them (92%) had severe underlying diseases. An in situ prosthetic graft replacement, mainly using cryopreserved arterial allografts, was performed in all patients, excepted one who underwent extra-anatomic bypass. Causative organisms were identified in 23 patients (92%). The in-hospital mortality rate was 48%. Among pre-operative characteristics, age ≥ 70 years, creatinine ≥ 12 mg/L and C reactive protein ≥ 50 mg/L were significantly associated with in-hospital mortality. Hospital mortality rates increased with the number of risk factor present on ICU admission, and were 0%, 14.3%, 85.7% and 100% for 0, 1, 2 and 3 factors, respectively. The only intra-operative factor associated with prognosis was an associated intestinal procedure due to aorto-enteric fistula. SAPS II, SOFA score and occurrence of medical or surgical complications were postoperative characteristics associated with in-hospital mortality.Conclusion: Morbidity and mortality associated with surgical approach of aortic graft infections are considerable. Age and values of creatinine and C Reactive protein on hospital admission appear as the most important determinant of in hospital mortality. They could be taken into account for guiding the surgical strategy. © 2014 Garot et al.; licensee BioMed Central Ltd.

Purpose: The main objective of this study was to detect subacute complications that can arise from laparoscopic Roux-en-Y gastric bypass and take a rational approach to manage these complications. Methods: A prospective observational study was performed from November 2010 to December 2012. All patients undergoing gastric bypass surgery for morbid obesity were included in this study. Patients with complications before day 5 were excluded from the study. Clinical and laboratory data (C-reactive protein, leukocyte count) at postoperative day 5, 30-day morbidity, were recorded. The diagnostic value of C-reactive protein (CRP) and leukocytes were determined by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. Results: One hundred and twenty-six patients were included. The overall incidence of 30-day morbidity was 8.7 %, and anastomotic leakage rate was 3.2 %. C-reactive protein at postoperative day 5 was a good predictor of complications (AUC was 0.862 (95 % CI [0.76; 0.96]; p<0.001) and anastomotic leakage (AUC was 0.863 (95 % CI [0.66; 1]; p=0.014). A CRP cutoff level of 136 mg/l at postoperative day 5 yielded a specificity of 95.5 % and a sensitivity of 57.1 % for the detection of postoperative complications. The negative predictive value was 94.6 %. A CRP level of 136 mg/l at day 5 was significantly associated with postoperative morbidity. Conclusions: C-reactive protein dosage at postoperative day 5 is a relevant predictor of postoperative complications permitting to select patients at risk. Radiological examination and close monitoring could be restricted to patients with CRP level exceeding 136 mg/l. © 2014 Springer-Verlag.

Object: Brainstem gliomas were regarded as a single entity prior to the advent of MRI; however, several studies investigating MRI have recognized that these lesions are a heterogeneous group, and certain subgroups have a better prognosis for long-term survival. The aim of this study was to conduct a retrospective analysis of prognostic factors of patients with brainstem gliomas confirmed by histopathological diagnosis, particularly regarding assessment of whether histological grade, age, and MRI findings are prognostic factors for patient survival. Methods: The study evaluated 100 patients diagnosed with brainstem glioma. There were 63 adults (40 men and 23 women; age range 18-75 years, mean 41 years) and 37 children (19 boys and 18 girls; age range 2-12 years, mean 6.9 years). Results: The mean overall survival of this population, measured from the date of biopsy, was 57 months for diffuse low-grade glioma and 13.8 months for diffuse high-grade glioma (p < 0.001). The mean survival among patients with nonenhancing contrast lesions on MRI was 54.2 months, whereas for patients with enhancing lesions, it was 21.7 months (p < 0.001). Comparisons between the Kaplan-Meier survival curves of adults and children revealed similar median survival periods of 25 and 16 months, respectively (p > 0.05). The multivariate analysis (Cox proportional hazards regression) revealed that only histological grade was a significant prognostic factor (p < 0.001). Conclusions: The study revealed that histological grade and MRI features were significant prognostic factors for survival in these patients, but in multivariate analysis, only histological grade remained a significant factor.

Potentially avoidable hospitalizations are studied as an indirect measure of access to primary care. Understanding the determinants of these hospitalizations can help improve the quality, efficiency, and equity of health care delivery. Few studies have tackled the issue of potentially avoidable hospitalizations in France, and none has done so at the national level. We assessed disparities in potentially avoidable hospitalizations in France in 2012 and analyzed their determinants. The standardized rate of potentially avoidable hospitalizations ranged from 0.1 to 44.4 cases per 1,000 inhabitants, at the ZIP code level. Increased potentially avoidable hospitalizations were associated with higher mortality, lower density of acute care beds and ambulatory care nurses, lower median income, and lower education levels. This study unveils considerable variation in the rate of potentially avoidable hospitalizations in spite of France's mandatory, publicly funded health insurance system. In addition to epidemiological and sociodemographic factors, this study suggests that primary care organization plays a role in geographic disparities in potentially avoidable hospitalizations that might be addressed by increasing the number of nurses and enhancing team work in primary care. Policy makers should consider measuring potentially avoidable hospitalizations in France as an indicator of primary care organization. ©2015 Project HOPE-The People-to-People Health Foundation, Inc.

The author, a child psychiatrist, calls for a dialogue between psychoanalysis and neuroscience (both from his clinical joint practices with neuropediatricians and on a theoretical level) to found a new approach to the questions of neurodevelopmental and psychopathological disorders. He briefly discusses two examples. The first example is developmental and concerns the links between the archaic grasping reflex and adhesive identification. He shows how the phenomena observed in the two fields can find a logical sequence. The second example concerns a therapeutic technique (wrapping) that is used to soothe self-injurious behaviours in children with autism. Here, again, both approaches are used to better understand the phenomenon in question. Bridges must be built to open new theoretico-clinical and therapeutic collaborations. One could imagine data integration from these two heterogeneous subdomains to form a new complex subdomain, from which productivity is guaranteed. © 2011.
