Patient versus general practitioner perception of problems with treatment adherence in type 2 diabetes: from adherence to concordance.

OBJECTIVES: To determine the prevalence of problems with treatment adherence among type-2 diabetic patients with regards to medication, dietary advice, and physical activity; to identify the associated clinical and psychosocial factors; and to investigate the degree of agreement between patient-perceived and GP-perceived adherence. METHODS: Consecutive patients were solicited during visits to 39 GPs. In total, 521 patients self-reported on treatment adherence, anxiety and depression, and disease perception. The GPs reported clinical and laboratory data and patients' adherence. A multivariate analysis identified the factors associated with adherence problems. RESULTS: Problems of adherence to medication, dietary advice, and physical activity recommendations were reported by 17%, 62%, and 47% of the patients, respectively. Six independent factors were found associated with adherence problems: young age, body-mass index (BMI) > 30 kg/m(2), glycosylated haemoglobin (HbA(1c)) > 8%, single life, depression, and perception of medication as a constraint. Agreement between patients' and GPs' assessments of treatment problems reached 70%. CONCLUSION: In type 2 diabetes, problems with dietary advice or physical activity are far more frequent than problems with medication, and not all physicians are fully aware of patients' problems. More active listening and shared decision-making should enhance adherence and improve outcomes.

A Randomized Controlled Trial Comparing Intradermal vs. Intramuscular Influenza Vaccine in Lung Transplant Recipients

Background: Immunogenicity of standard infl uenza vaccine is suboptimal in lung transplant recipients. Intradermal vaccine may elicit stronger responses due to recruitment of local dendritic cells. We compared the immunogenicity of the infl uenza vaccine administered intradermally (ID) to the standard intramuscular (IM) vaccination. Methods: In this investigator-blinded, two-center, prospective trial, lung transplant patients were randomized to receive intradermal (6ug) or intramuscular (15ug) 2008/9 trivalent inactivated infl uenza vaccine. Immunogenicity was evaluated using a standard hemagglutination inhibition assay (HIA). Response to the vaccine was defi ned as a fourfold increase of the HIA levels for any of the 3 viral strains in the vaccine. Geometric mean titers (GMT) and seroprotection rate (HIA ≥32) were also analyzed. Patients were followed during 6 months for the development of infl uenza or acute rejection. Results: We randomized 84 patients to receive the ID (n=41) vs. IM (n=43) vaccine, respectively. Baseline characteristics were similar between groups. Median time from transplantation was 3.4 yrs (ID) vs. 3.3 yrs (IM) (p=0.84). Vaccine response to at least one antigen was seen in 6/41 (14.6%) patients in the ID vs. 8/43 (18.6%) in the IM group (p=0.77). In the ID group, GMTs (95% CI) after vaccination were 15.7 (11.1-22.3) for H1N1, 84.0 (52.0-135.7) for H3N2, and 14.5 (9.6-21.8) for B strains vs. in the IM group 17.5 (11.8-25.9) for H1N1, 108.9 (77.5-153.2) for H3N2, and 20.2 (12.8-31.9) for B (p=NS, all 3 strains). Seroprotection was 39% (H1N1), 82.9% (H3N2) and 29.3% (B strain) in the ID group vs. 27.9% (H1N1), 97.7% (H3N2) and 58.1% (B strain) in the IM group. No factors associated with vaccine response were identifi ed. Mild adverse events were seen in 44% of patients (ID) vs. 34% (IM) (p=0.38). Two patients (4.8%) in the ID group developed infl uenza infection compared to none in the IM group. Two patients in each group developed biopsy-proven acute rejection during follow-up. Conclusions: Immunogenicity of the 2008/09 infl uenza vaccine was poor in lung transplant recipients. ID administration of the vaccine elicited similar immune responses to standard IM vaccination. Novel strategies of vaccination are needed to protect lung transplant recipients from infl uenza.

The effect of fluoxetine on the pharmacokinetics and safety of risperidone in psychotic patients

In this open, 30-day trial, the pharmacokinetics, safety and tolerability of a combination therapy of risperidone (4 or 6 mg/day)and fluoxetine (20mg/day from day 6) were evaluated in 11 psychotic inpatients. CYP2D6 genotyping revealed that 3 and 8 patients were poor metabolizers (PMs) and extensive metabolizers (EMs) of debrisoquine, respectively. The mean (+/- SD) AUC of risperidone increased from 83.1 +/- 46.8 ng.h/ml and 398.3 +/- 33.2 ng.h/ml (monotherapy) to 345.1 +/- 158.0 ng.h/ml (p < 0.05) and 514.0 +/- 144.2 ng.h/ml (p < 0.001) when coadministered with fluoxetine in EMs and PMs, respectively. The AUC of the active moiety (risperidone plus 9-hydroxy-risperidone) increased from 470.0 +/- 170.0 ng.h/ml to 663.0 +/- 243.3 ng.h/ml (p < 0.05)and from 576.3 +/- 19.6 ng.h/ml to 788.0 +/- 89.1 ng.h/ml (ns) in EMs and PMs, respectively. In EMs, the AUC of 9-hydroxy-risperidone remained similar (monotherapy vs. combination therapy: 386.8 +/- 153.0 ng.h/ml vs. 317.7 +/- 125.2 ng.h/ml, ns),whereas it increased in PMs (178.3 +/- 23.5 ng.h/ml vs. 274.0 +/- 55.1 ng.h/ml (p < 0.05)). Ten of the 11 patients showed a clinical improvement (reduction of 20% or more in total PANSS score and 70% on the mean MADRS score compared to baseline). The severity and incidence of extrapyramidal symptoms and adverse events did not significantly increase when fluoxetine was added.

Prenatal management of monoamniotic twin pregnancies.

OBJECTIVE: To evaluate antenatal surveillance strategies and the optimal timing of delivery for monoamniotic twin pregnancies. METHODS: Obstetric and perinatal outcomes were retrospectively retrieved for 193 monoamniotic twin pregnancies. Fetal and neonatal outcomes were compared between fetuses followed in an inpatient setting and those undergoing intensive outpatient follow-up from 26 to 28 weeks of gestation until planned cesarean delivery between 32 and 35 weeks of gestation. The risk of fetal death was compared with the risk of neonatal complications. RESULTS: Fetal deaths occurred in 18.1% of fetuses (70/386). Two hundred ninety-five neonates from 153 pregnancies were born alive after 23 weeks of gestation. There were 17 neonatal deaths (5.8%), five of whom had major congenital anomalies. The prospective risk of a nonrespiratory neonatal complication was lower than the prospective risk of fetal death after 32 4/7 weeks of gestation (95% confidence interval 32 0/7-33 4/7). The incidence of death or a nonrespiratory neonatal complication was not significantly different between fetuses managed as outpatients (14/106 [13.2%]) or inpatients (15/142 [10.5%]; P=.55). Our statistical power to detect a difference in outcomes between these groups was low. CONCLUSIONS: The in utero risk of a monoamniotic twin fetus exceeds the risk of a postnatal nonrespiratory complication at 32 4/7 weeks of gestation. If close fetal surveillance is instituted after 26-28 weeks of gestation and delivery takes place at approximately 33 weeks of gestation, the risk of fetal or neonatal death is low, no matter the surveillance setting. LEVEL OF EVIDENCE: : II.

Émergence du moi cérébral de Theodor Meynert à Antonio Damasio = Emergence of the cerebral self, from Theodor Meynert to Antonio Damasio

Antonio Damasio's works have brought emotions into line with current trends in neuroscience. They are conceived as the addition, to a perception, of the somatic effects it has induced. Nevertheless, this continuous and relatively steady process of body perception has also led to the less-known hypothesis of the "neural self." Behind the explicit and apparently contradictory reference to William James and Sigmund Freud, there lies a common source: Theodor Meynert's conception of a "cortical self." Our aim is to enlight a stream unified around what we call here "cerebral self." The Self is thus considered as the cerebral projection or presentation of the body. The specificity of this notion is particularly highlighted by its confrontation to the closely, yet disembodied, notion of "cerebral subject.". Pour citer cette revue : Psychiatr. Sci. Hum. Neurosci. 9 (2011).

Reduction of corneal edema in endotoxin-induced uveitis after application of L-NAME as nitric oxide synthase inhibitor in rats by iontophoresis.

PURPOSE: To investigate the involvement of the cornea during endotoxin-induced uveitis (EIU) in the rat and the effect of Ngamma-nitro-L-arginine methyl ester (L-NAME) as nitric oxide synthase (NOS) inhibitor, administered by iontophoresis. METHODS: EIU was induced in Lewis rats that were killed at 8 and 16 hours after lipopolysaccharide (LPS) injection. The severity of uveitis was evaluated clinically at 16 hours, and nitrite levels were evaluated in the aqueous humor at 8 hours. Corneal thickness was measured, 16 hours after LPS injection, on histologic sections using an image analyzer. Transmission electron microscopy (TEM) was used for fine analysis of the cornea. Transcorneoscleral iontophoresis of L-NAME (100 mM) was performed either at LPS injection or at 1 and 2 hours after LPS injection. RESULTS: At 16 hours after LPS injection, mean corneal thickness was 153.7+/-5.58 microm in the group of rats injected with LPS (n=8) compared with 126.89+/-11.11 microm in the saline-injected rats (n=8) (P < 0.01). TEM showed stromal edema and signs of damage in the endothelial and epithelial layers. In the group of rats treated by three successive iontophoreses of L-NAME (n=8), corneal thickness was 125.24+/-10.36 microm compared with 146.76+/-7.52 microm in the group of rats treated with iontophoresis of saline (n=8), (P=0.015). TEM observation showed a reduction of stromal edema and a normal endothelium. Nitrite levels in the aqueous humor were significantly reduced at 8 hours by L-NAME treatment (P=0.03). No effect on corneal edema was observed after a single iontophoresis of L-NAME at LPS injection (P=0.19). Iontophoresis of saline by itself induced no change in corneal thickness nor in TEM structure analysis compared with normal rats. CONCLUSIONS: Corneal edema is observed during EIU. This edema is significantly reduced by three successive iontophoreses of L-NAME, which partially inhibited the inflammation. A role of nitric oxide in the corneal endothelium functions may explain the antiedematous effect of L-NAME.

Cytochrome b haplotype divergences in West European Apodemus

Sequencing of the cytochrome b mitochondrial gene (732 base pairs) in samples of Apodemus sylvaticus from Central Europe (eastern France, Switzerland, southern Germany and western Austria) revealed significant molecular variation not reflected in previous morphological and genetic studies of this species. A comparison with the sequences (150 bp) of 54 specimens available from GenBank (NCBI) showed that two problematic individuals originating from southern Germany have to be assigned to A. fulvipectus, a species not yet known in western Europe. A. sylvaticus specimens (n = 14) sampled north of the Alps exhibited a maximum intraspecific sequence divergence of about 5.1%, whereas the maximum divergence is much Lower in A. flavicollis (1%, n = 5) and in A. alpicola (0.5%, n = 4), although the samples originate from a similar geographic range of about 350 km. We also found a high rate of erroneously assigned specimens in GenBank, which indicates that the discrimination of Apodemus species remains a problem and requires further investigations.

Factors influencing the adoption of an innovation: an examination of the uptake of the Canadian Heart Health Kit (HHK)

BACKGROUND: There is an emerging knowledge base on the effectiveness of strategies to close the knowledge-practice gap. However, less is known about how attributes of an innovation and other contextual and situational factors facilitate and impede an innovation's adoption. The Healthy Heart Kit (HHK) is a risk management and patient education resource for the prevention of cardiovascular disease (CVD) and promotion of cardiovascular health. Although previous studies have demonstrated the HHK's content validity and practical utility, no published study has examined physicians' uptake of the HHK and factors that shape its adoption. OBJECTIVES: Conceptually informed by Rogers' Diffusion of Innovation theory, and Theory of Planned Behaviour, this study had two objectives: (1) to determine if specific attributes of the HHK as well as contextual and situational factors are associated with physicians' intention and actual usage of the HHK kit; and (2), to determine if any contextual and situational factors are associated with individual or environmental barriers that prevent the uptake of the HHK among those physicians who do not plan to use the kit. METHODS: A sample of 153 physicians who responded to an invitation letter sent to all family physicians in the province of Alberta, Canada were recruited for the study. Participating physicians were sent a HHK, and two months later a study questionnaire assessed primary factors on the physicians' clinical practice, attributes of the HHK (relative advantage, compatibility, complexity, trialability, observability), confidence and control using the HHK, barriers to use, and individual attributes. All measures were used in path analysis, employing a causal model based on Rogers' Diffusion of Innovations Theory and Theory of Planned Behaviour. RESULTS: 115 physicians (follow up rate of 75%) completed the questionnaire. Use of the HHK was associated with intention to use the HHK, relative advantage, and years of experience. Relative advantage and the observability of the HHK benefits were also significantly associated with physicians' intention to use the HHK. Physicians working in solo medical practices reported experiencing more individual and environmental barriers to using the HHK. CONCLUSION: The results of this study suggest that future information innovations must demonstrate an advantage over current resources and the research evidence supporting the innovation must be clearly visible. Findings also suggest that the innovation adoption process has a social element, and collegial interactions and discussions may facilitate that process. These results could be valuable for knowledge translation researchers and health promotion developers in future innovation adoption planning.

Burnout levels among Portuguese family doctors: a nationwide survey

AIM: To characterise the prevalence of burnout syndrome in a sample of family doctors (FDs) working in the Portuguese National Health System. DESIGN: Cross-sectional survey. SETTING: Primary healthcare centres from the 18 continental districts and two archipelagos of Portugal. METHOD: The Portuguese version of the Maslach Burnout Inventory-Human Services Survey was sent to 40 randomly selected healthcare centres and distributed to the FDs employed. Socio-demographic and work-related data were also collected. Participants were classified as having high, average or low levels of emotional exhaustion (EE), depersonalisation (DP) and personal accomplishment (PA) dimensions of burnout. RESULTS: 371 questionnaires were sent, of which 153 (83 women, age range 29-64 years; response rate 41%) returned. One-quarter (25.3%, 95% CI 18.6% to 33.1%) of FDs scored high for EE, 16.2% (10.7% to 23.2%) for DP and 16.7% (11.1% to 23.6%) for lack of PA. On multivariate analysis, being married, of older age, having many years of practice or working in a personalised healthcare unit tended to be associated with increased burnout components. Men tended to present higher EE and DP but lower lack of PA than women. Finally, the prevalence (95% CI) of burnout ranged between 4.1% (1.5% to 8.6%) and 32.4% (25.0% to 40.6%), depending on the definition used. CONCLUSIONS: High burnout is relatively common among Portuguese FDs. Burnout relief measures should be developed in order to prevent a further increase of burnout syndrome among Portuguese FDs.

Diffuse large B-cell lymphoma of Waldeyer's ring has distinct clinicopathologic features: a GELA study.

BACKGROUND: Diffuse large B-cell lymphomas (DLBCLs) arising in specific extranodal sites have peculiar clinicopathologic features. PATIENTS AND METHODS: We analyzed a cohort of 187 primary Waldeyer's ring (WR) DLBCLs retrieved from GELA protocols using anthracyclin-based polychemotherapy. RESULTS: Most patients (92%) had stage I-II disease. A germinal center B-cell-like (GCB) immunophenotype was observed in 61%, and BCL2 expression in 55%, of WR DLBCLs. BCL2, BCL6, IRF4 and MYC breakpoints were observed in, respectively, 3 of 42 (7%), 9 of 36 (25%), 2 of 26 (8%) and 4 of 40 (10%) contributive cases. A variable follicular pattern was evidenced in 30 of 68 (44%) large biopsy specimens. The 5-year progression-free survival (PFS) and the overall survival (OS) of 153 WR DLBCL patients with survival information were 69.5% and 77.8%, respectively. The GCB immunophenotype correlated with a better OS (P = 0.0015), while BCL2 expression predicted a worse OS (P = 0.037), an effect overcome by the GCB/non-GCB classification. Compared with matched nodal DLBCLs, WR DLBCLs with no age-adjusted international prognostic index factor disclosed a better 5-year PFS rate (77.5% versus 70.7%; P = 0.03). CONCLUSIONS: WR DLBCLs display distinct clinicopathologic features compared with conventional DLBCLs, with usual localized-stage disease, common follicular features and a high frequency of GCB immunophenotype contrasting with a low rate of BCL2 rearrangements. In addition, they seem to be associated with a better outcome than their nodal counterpart.

Approches exégétiques du Deutéronome. Brève histoire de la recherche sur le Deutéronome depuis Martin Noth.

Depuis la parution des Überlieferungsgeschitliche Studien de Martin Noth, le livre du Deutéronome joue un rôle central dans la discussion exégétique. L'A. cherche à faire le point sur le chemin parcouru depuis cinquante ans. Au niveau diachronique, aucun consensus n'apparaît sur les questions de la datation et des rédactions successives. Le modèle le plus performant semble être Deutéronome primitif sous Josias suivi à l'époque de l'exil de son insertion dans l'historiographie, puis de plusieurs retouches rédactionnelles. Au niveau théologique, les thèmes de la loi, de l'alliance, du pays, de l'exode et des pères en sont l'épine dorsale

Place de la laparoscopie dans le traitement du cancer de l'endomètre [Laparoscopy in the management of endometrial cancer]

Les récents progrès de la laparoscopie ont modifié l'approche chirurgicale des patientes atteintes d'un cancer de l'endomètre. Le centre Swissendos Fribourg en collaboration avec l'AGO (Groupe de travail pour la gynécologie oncologique) et l'AGE (Groupe de travail pour la gynécologie endoscopique) ont entrepris d'élaborer un consensus basé sur l'évidence pour la pratique de la laparoscopie dans le traitement du cancer de l'endomètre. L'objectif a été de définir une approche propre à la Suisse en fournissant aux praticiens une aide à la prise en charge. Recent advance in laparoscopy have changed the surgical approach of endometrial cancer patients. The Swissendos Center, Fribourg, in collaboration with AGO (Groupe de travail pour la gynécologie oncologique) and AGE (groupe de travail pour la gynécologie endoscopique) have established a consensus based on the available evidence for the use of laparoscopy in the management of patients with endometrial cancer The main objective was to define Swiss clinical practice guidelines appropriate to the country and consistent with the needs of the physicians.
