Assessment of parental discipline in daily life.

The use of ecological momentary assessment (EMA) for studying parenting has been rare. We examined the psychometric properties and structural validity of an EMA Parenting Scale based on 32 mothers' reports of their parenting over a period of 10 consecutive days, and explored the acceptance of the scale and compliance with the procedure. The results suggested that the EMA Parenting Scale was well accepted for the assessment of daily parenting, and that it consistently captured the overreactive and lax dimensions of parenting across different episodes of child misbehavior. Moreover, multilevel analyses suggested that the scale was sensitive to change across different parenting episodes, and that it reliably assessed the dimensions at both the personal and situational levels.

Diabète et démence: tes liaisons dangereuses [Diabetes and dementia: the dangerous liaisons? ].

As population ages, a growing number of older patients present the constellation of diabetes and dementia. Numerous recent studies highlight that diabetes may increase the risk for Alzheimer and vascular dementia. Among patients with previous severe hypoglycemia, that risk may even double. Inversely demented patients have about three times higher risk of hypoglycemia. Given that spiral link between hypoglycemia and dementia, the latter should be considered as a possible complication of diabetes and consistently be screened for among older diabetic patients. Furthermore, the American Diabetes Association and American Geriatric Society consensus recommends a more flexible glycemic treatment goal of AIC among demented patients, with a target range between 8 and 9%.

Diabetes and pre-diabetes are associated with cardiovascular risk factors and carotid/femoral intima-media thickness independently of markers of insuline resistance and adiposity

Background Impaired glucose regulation (IGR) is associated with detrimental cardiovascular outcomes such as cardiovascular disease risk factors (CVD risk factors) or intima-media thickness (IMT). Our aim was to examine whether these associations are mediated by body mass index (BMI), waist circumference (waist) or fasting serum insulin (insulin) in a population in the African region. Methods Major CVD risk factors (systolic blood pressure, smoking, LDL-cholesterol, HDL-cholesterol,) were measured in a random sample of adults aged 25-64 in the Seychelles (n=1255, participation rate: 80.2%). According to the criteria of the American Diabetes Association, IGR was divided in four ordered categories: 1) normal fasting glucose (NFG), 2) impaired fasting glucose (IFG) and normal glucose tolerance (IFG/NGT), 3) IFG and impaired glucose tolerance (IFG/IGT), and 4) diabetes mellitus (DM). Carotid and femoral IMT was assessed by ultrasound (n=496). Results Age-adjusted levels of the major CVD risk factors worsened gradually across IGR categories (NFG < IFG/NGT < IFG/IGT < DM), particularly HDL-cholesterol and blood pressure (p for trend <0.001). These relationships were marginally attenuated upon further adjustment for waist, BMI or insulin (whether considered alone or combined) and most of these relationships remained significant. With regards to IMT, the association was null with IFG/NGT, weak with IFG/IGT and stronger with DM (all more markedly at femoral than carotid levels). The associations between IMT and IFG/IGT or DM (adjusted by age and major CVD risk factors) decreased only marginally upon further adjustment for BMI, waist or insulin. Further adjustment for family history of diabetes did not alter the results. Conclusions We found graded relationships between IGR categories and both major CVD risk factors and carotid/femoral IMT. These relationships were only partly accounted for by BMI, waist and insulin. This suggests that increased CVD-risk associated with IGR is also mediated by factors other than the considered markers of adiposity and insulin resistance. The results also imply that IGR and associated major CVD risk factors should be systematically screened and appropriately managed.

Unexpected Role for Connexin37 in Circulating FVIII and Coagulation

The gap junction protein connexin37 (Cx37) plays an important role in cell-cell communication in the vasculature. Cx37 is expressed in endothelial cells, platelets and megakaryocytes. We have recently shown that Cx37 limits thrombus propensity by permitting intercellular signaling between aggregating platelets. Here, we have performed high throughput phage display to identify potential binding partners for the regulatory intracellular C-terminus of Cx37 (Cx37CT). We retrieved 2 consensus binding motifs for Cx37CT: WHK...[K,R]XP... and FH-K...[K,R]XXP.... Sequence alignment against the NCBI protein database indicated 66% homology of one the selected peptides with FVIII B-domain. We performed cross-linking reactions using BS3 and confirmed that an 11-mer peptide of the FVIII B-domain sequence linked to recombinant Cx37CT. In vitro binding of this peptide to Cx37CT was also confirmed by surface plasmon resonance. The dissociation constant of FVIII B-domain peptides to Cx37CT was ~20 uM. Other peptide sequences, designed upstream or downstream of the FVIII B-domain sequence, showed very low or no affinity for Cx37CT. Finally, in vivo studies revealed that thrombin generation in platelet-poor plasma from Cx37-/- mice (endogenous thrombin potential: 634±11 nM min, mean±SEM) was increased compared to Cx37+/+ mice (427±12, P<0.001). Moreover, partial activated thromboplastin time (aPTT) was shorter in Cx37-/- (39.7±1.5 s) than in Cx37+/+ mice (45.9±1.8, P=0.03), whereas prothrombin time was comparable. The shorter aPTT in Cx37-/- mice correlated with higher circulating FVIII activity (46.0±0.7 vs. 53.5±2.7 s for Cx37+/+, P=0.03). Overall, our data show for the first time a functional interaction between FVIII and Cx37. This interaction may be relevant for the control of FVIII secretion and, thereby, in the regulation of levels of FVIII circulating in blood. In addition, these results may open new perspectives to improve the efficiency of recombinant FVIII manufacturing.

Does CRP Play a Causal Role in the Development of Coronary Heart Disease: Results of a Mendelian Randomisation Experiment Involving 128,935 People

Background: C-reactive protein (CRP) is associated with risk of coronary heart disease (CHD). Whether CRP is causally associated with CHD or merely a marker of underlying atherosclerosis is uncertain. Methods: We used a Mendelian randomisation design to investigate the causal relationship of CRP with CHD. We identified three genetic variants in the CRP locus (rs7553007, rs1130864 and rs1205) which influence CRP levels. We tested the three SNPs for association with CHD amongst 28,112 CHD cases and 100,823 controls. We then compared the observed relationship between the SNPs and CHD, with that predicted from the association of SNPs with CRP levels, and of CRP levels with CHD. Results: SNPs in the CRP locus were not associated with CHD: rs7553007, OR 0.98 (95% CI, 0.94-1.01); rs1130864, OR 1.00 (95% CI, 0.86-1.15); rs1205, OR 1.03 (95% CI, 0.99-1.07); combined OR for all three SNPs, 1.00 (95% CI, 0.97-1.02), per 20% lower CRP (figure). In contrast, the predicted OR for CHD from a 20% lower CRP level is 0.94 (95% CI, 0.94- 0.95), based on meta-analysis of observational studies. Conclusions: Though CRP variants are associated with CRP levels, and CRP levels with risk of CHD, we observed that CRP variants are not associated with CHD risk. Our Mendelian randomisation experiment strongly argues against a causal association of CRP with CHD.

Career interventions for adults frequently include personality assessment. Personality in career counseling contexts should no longer be considered as vocational personality associated with personality interests but, rather, as a set of dispositions that has an impact on several vocational and career-related outcomes, such as work engagement, work satisfaction, job performance, etc. Although the relationship between personality and the vocational and career related outcomes is not direct, it might certainly be mediated by several regulatory processes, such as work adaptability, and moderated by contextual and environmental factors. Personality assessment initiates an individual's self-regulatory process and contributes to the overall effectiveness of career interventions when feedback is individualized and stimulates a deconstruction, reconstruction, and co-construction of the vocational or multiple self-concept. Personality assessments can also promote the reconstruction of a self-concept more aligned with the perception of the environment about the personality of the counselee, strengthening the reality principle allowing more rational and controlled choices. In addition, some specific personality profiles, such as having high levels of neuroticism and low levels of conscientiousness, can be considered as risk factors frequently leading to career decision-making difficulties. Moreover, people with low conscientiousness benefit less from career interventions, so special attention should be devoted to counselees having that characteristic. Two case studies are provided to illustrate these important aspects of personality assessment in career interventions.

Arginase II Promotes Macrophage Inflammatory Responses Through Mitochondrial Reactive Oxygen Species, Contributing to Insulin Resistance and Atherogenesis.

BACKGROUND: Macrophage-mediated chronic inflammation is mechanistically linked to insulin resistance and atherosclerosis. Although arginase I is considered antiinflammatory, the role of arginase II (Arg-II) in macrophage function remains elusive. This study characterizes the role of Arg-II in macrophage inflammatory responses and its impact on obesity-linked type II diabetes mellitus and atherosclerosis. METHODS AND RESULTS: In human monocytes, silencing Arg-II decreases the monocytes' adhesion to endothelial cells and their production of proinflammatory mediators stimulated by oxidized low-density lipoprotein or lipopolysaccharides, as evaluated by real-time quantitative reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay. Macrophages differentiated from bone marrow cells of Arg-II-deficient (Arg-II(-/-)) mice express lower levels of lipopolysaccharide-induced proinflammatory mediators than do macrophages of wild-type mice. Importantly, reintroducing Arg-II cDNA into Arg-II(-/-) macrophages restores the inflammatory responses, with concomitant enhancement of mitochondrial reactive oxygen species. Scavenging of reactive oxygen species by N-acetylcysteine prevents the Arg-II-mediated inflammatory responses. Moreover, high-fat diet-induced infiltration of macrophages in various organs and expression of proinflammatory cytokines in adipose tissue are blunted in Arg-II(-/-) mice. Accordingly, Arg-II(-/-) mice reveal lower fasting blood glucose and improved glucose tolerance and insulin sensitivity. Furthermore, apolipoprotein E (ApoE)-deficient mice with Arg-II deficiency (ApoE(-/-)Arg-II(-/-)) display reduced lesion size with characteristics of stable plaques, such as decreased macrophage inflammation and necrotic core. In vivo adoptive transfer experiments reveal that fewer donor ApoE(-/-)Arg-II(-/-) than ApoE(-/-)Arg-II(+/+) monocytes infiltrate into the plaque of ApoE(-/-)Arg-II(+/+) mice. Conversely, recipient ApoE(-/-)Arg-II(-/-) mice accumulate fewer donor monocytes than do recipient ApoE(-/-)Arg-II(+/+) animals. CONCLUSIONS: Arg-II promotes macrophage proinflammatory responses through mitochondrial reactive oxygen species, contributing to insulin resistance and atherogenesis. Targeting Arg-II represents a potential therapeutic strategy in type II diabetes mellitus and atherosclerosis. (J Am Heart Assoc. 2012;1:e000992 doi: 10.1161/JAHA.112.000992.).

Salmonella epidural abscess in sickle cell disease: failure of the nonsurgical treatment.

In patients suffering from sickle cell disease (SCD), bone is a preferred site of infection. We report the case of a five-year-and-eight-month-old black African boy with homozygous-SS disease who developed a cranial epidural abscess. This intracranial infectious complication originated from a Salmonella enteritidis osteitis of the frontal bone. Antibiotic treatment alone did not control the disease, so surgery was necessary to remove the necrotic bone and to evacuate the epidural pus. The numerous factors interfering with normal healing of a septic focus in sickle cell anemia, particularly in this previously undescribed intracranial complication, emphasize the need for a primary and early surgical treatment in similar situations.

Prise en charge du cholestérol pour prévenir le risque cardiovasculaire:recommandations américaines 2013.Prise de position du Groupe de travail Suisse Lipides et Athérosclérose (GSLA).

Les dernières recommandations américaines de l'American College of Cardiology et de l'American Heart Association proposent d'abaisser le seuil de prescription de statines pour la prévention cardiovasculaire primaire, et d'abandonner les cibles de LDL-cholestérol pour utiliser le plus souvent des statines de haute intensité. Le Groupe de travail Suisse Lipides et Athérosclérose (GSLA) pense que ces recommandations ne devraient pas être appliquées en Suisse, car elles augmenteraient très fortement le nombre de personnes à bas risque sous statines, chez qui le rapport bénéfice/risque au long cours est incertain, et pourraient diminuer l'importance du style de vie, première priorité dans la prévention cardiovasculaire primaire. En outre, l'abandon des cibles de LDL-cholestérol limite l'individualisation de la prise en charge quant au choix du type et du dosage de la statine, et pourrait diminuer l'adhérence thérapeutique. Pour ces raisons, le GSLA recommande de poursuivre avec les stratégies de prévention bien établies en Suisse et résumées dans les recommandations du GSLA 2012.

Training needs in adolescent medicine of practising doctors: a Swiss national survey of six disciplines.

OBJECTIVE: To assess and compare the training needs in adolescent medicine of doctors within 6 specialties as a basis for the development of pre/postgraduate and continuing medical education (CME) training curricula. DESIGN: Cross-sectional postal survey. SETTING: Switzerland. PARTICIPANTS: National, representative, random sample of 1857 practising doctors in 6 disciplines (general practitioners, paediatricians, gynaecologists, internists, psychiatrists, child psychiatrists) registered with the Swiss Medical Association. MAIN OUTCOME MEASURES: Perceived importance of and training interest in 35 topics related to adolescent medicine listed in a self-administered, anonymous questionnaire. RESULTS: A total of 1367 questionnaires were returned, representing a response rate of 73.9%. Clear interest in adolescent medicine was reported by 62.1% of respondents. Topics perceived to be the most important in everyday practice were functional symptoms (71.4%), acne (67.1%), obesity (64.6%), depression-anxiety (68.1%) and communication with adolescents (61.7%). Differences between disciplines were especially marked for gynaecologists, who expressed interest almost exclusively in medical topics specific to their field. In contrast, other disciplines commonly reported a keen interest in psychosocial problems. Accordingly, interest in further training was expressed mostly for functional symptoms (62.4%), eating disorders (56.3%), depression-anxiety (53.7%) and obesity (52.6%). Issues related to injury prevention, chronic disease and confidentiality were rated as low priorities. CONCLUSIONS: Regardless of discipline, Swiss primary care doctors expressed a strong interest in adolescent medicine. Continuing medical education courses should include both interdisciplinary courses and discipline-specific sessions. Further training should address epidemiological and legal/ethical issues (e.g. injury prevention, confidentiality, impact of chronic conditions).

Traitement pharmacologique de la schizophrénie : évaluation comparative de la qualité des recommandations de pratique clinique = Comparative evaluation of clinical practice guidelines for the treatment of schizophrenia

De nombreuses recommandations de pratique clinique (RPC) ont été publiées, en réponse au développement du concept de la médecine fondée sur les preuves et comme solution à la difficulté de synthétiser et trier l'abondante littérature médicale. Pour faire un choix parmi le foisonnement de nouvelles RPC, il est primordial d'évaluer leur qualité. Récemment, le premier instrument d'évaluation standardisée de la qualité des RPC, appelé " AGREE " pour appraisal of guidelines for research and evaluation, a été validé. Nous avons comparé - avec l'aide de la grille " AGREE " - les six principales RPC publiées depuis une dizaine d'années sur le traitement de la schizophrénie : (1) les Recommandations de l'Agence nationale pour le développement de l'évaluation médicale (ANDEM) ; (2) The American Psychiatric Association (APA) practice guideline for the treatment of patients with schizophrenia ; (3) The quick reference guide of APA practice guideline for the treatment of patients with schizophrenia [APA - guide rapide de référence] ; (4) The schizophrenia patient outcomes research team (PORT) treatment recommandations ; (5) The Texas medication algorithm project " T-MAP " ; (6) The expert consensus guideline for the treatment of schizophrenia. Les résultats de notre étude ont ensuite été comparés avec ceux d'une étude similaire publiée en 2005 par Gæbel et al. portant sur 24 RPC abordant le traitement de la schizophrénie, réalisée également avec l'aide de la grille " AGREE " et deux évaluateurs [Br J Psychiatry 187 (2005) 248-255]. De manière générale, les scores des deux études ne sont pas trop éloignés et les deux évaluations globales des RPC convergent : chacune des six RPC est perfectible et présente différemment des points faibles et des points forts. La rigueur d'élaboration des six RPC est dans l'ensemble très moyenne, la prise en compte de l'opinion des utilisateurs potentiels est lacunaire et un effort sur la présentation des recommandations faciliterait leur utilisation clinique. L'applicabilité des recommandations est également peu considérée par les auteurs. Globalement, deux RPC se distinguent et peuvent être fortement recommandées selon les critères de la grille " AGREE " : " l'APA - guide rapide de référence " et le " T-MAP ".

Efficiency of coronary artery disease screening guidelines in asymptomatic and atypical chest pain type 2 diabetic patients

RESUME Objectifs. Évaluer la prévalence de maladie coronarienne chez les patients diabétiques de type 2 asymptomatiques ou avec angor atypique selon les recommandations américaines de l'American Diabetes Association et de l'American College of Cardiology. Méthodes. Cent cinquante-quatre patients diabétiques de type 2 asymptomatiques ou avec angor atypique et présentant au minimum 2 facteurs de risque cardio-vasculaires additionnels ont été dépistés par échocardiographie de stress (71%, n=109), scintigraphie myocardique de perfusion (26%, n=40) ou l'association des 2 examens (3%, n=5). Résultats. L'échocardiographie de stress s'est révélée positive chez 16 patients (14%) et 14 ont eu une coronarographie révélant des sténoses significatives chez 12 (86%). La scintigraphie myocardique de perfusion était positive chez 16 patients (36%). Huit patients ont eu une coronarographie et 4 (50%) présentaient des sténoses significatives. Au total, 31 patients (20%) ont montré des signes d'ischémie lors de l'examen non-invasif et 15 (10%) ont présenté des sténoses significatives à la coronarographie. Les facteurs prédictifs indépendants de la maladie coronarienne étaient le tabagisme (OR 6.5, p=0.05), la microalbuminurie (OR 3.9, p=0.03), ainsi que les souffles fémoraux (OR 17.1, p=0.008). Conclusions. En suivant les recommandations américaines, un patient sur cinq présentait une ischémie lors des examens non-invasifs, tandis que 1 sur 10 avait des sténoses significatives à la coronarographie. L'analyse multivariée suggère que des marqueurs des complications micro- et macro-vasculaires en combinaison avec des facteurs de risque cardio-vasculaire classiques pourraient améliorer le pouvoir diagnostic de ces recommandations. SUMMARY Aims. We evaluated the prevalence of coronary artery disease in asymptomatic and atypical chest pain type 2 diabetic patients according to the American Diabetes Association and American College of Cardiology guidelines. Methods. Asymptomatic or atypical chest pain type 2 diabetic patients (n=154), with at least two additional cardiovascular risk factors, were screened for coronary artery disease using stress echocardiography (71%, n=109), myocardial perfusion imaging (26%, n=40) or both (3%, n=5). Results. Stress echocardiography was positive in 16 patients (14%) and 14 had a coronary angiography, revealing significant stenoses in 12 (86%). Myocardial perfusion imaging was positive in 16 patients (36%). Eight patients underwent angiography and 4 (50%) presented significant stenoses. Overall, 31 patients (20%) demonstrated signs of ischemia on non-invasive tests and 15 (10%) presented significant stenoses on coronary angiography. Independent predictors of coronary artery disease were smoking (OR 6.5, p=0.05), microalbuminuria (OR 3.9, p=0.03) and femoral murmur (OR 17.1, p=0.008). Conclusions. Following the guidelines, one in five diabetic patient presented ischemia on noninvasive tests, while one in ten presented significant coronary stenoses. Multivariate analysis suggests that adding markers of micro- and macro-vascular complications to classical cardiovascular risk factors may enhance the diagnostic efficiency of the guidelines.
