Current cardiovascular risk management patterns with special focus on lipid lowering in daily practice in Switzerland.

Background: There may be a considerable gap between LDL cholesterol (LDL-C) and blood pressure (BP) goal values recommended by the guidelines and results achieved in daily practice. Design Prospective cross-sectional survey of cardiovascular disease risk profiles and management with focus on lipid lowering and BP lowering in clinical practice. Methods: In phase 1, the cardiovascular risk of patients with known lipid profile visiting their general practitioner was anonymously assessed in accordance to the PROCAM-score. In phase 2, high-risk patients who did not achieve LDL-C goal less than 2.6 mmol/l in phase 1 could be further documented. Results: Six hundred thirty-five general practitioners collected the data of 23 892 patients with known lipid profile. Forty percent were high-risk patients (diabetes mellitus or coronary heart disease or PROCAM-score >20%), compared with 27% estimated by the physicians. Goal attainment rate was almost double for BP than for LDL-C in high-risk patients (62 vs. 37%). Both goals were attained by 25%. LDL-C values in phase 1 and 2 were available for 3097 high-risk patients not at LDL-C goal in phase 1; 32% of patients achieved LDL-C goal of less than 2.6 mmol/l after a mean of 17 weeks. The most successful strategies for LDL-C reduction were implemented in only 22% of the high-risk patients. Conclusion: Although patients at high cardiovascular risk were treated more intensively than low or medium risk patients, the majority remained insufficiently controlled, which is an incentive for intensified medical education. Adequate implementation of Swiss and International guidelines would expectedly contribute to improved achievement of LDL-C and BP goal values in daily practice.

Electrical source imaging for presurgical focus localization in epilepsy patients with normal MRI.

PURPOSE: Patients with magnetic resonance (MR)-negative focal epilepsy (MRN-E) have less favorable surgical outcomes (between 40% and 70%) compared to those in whom an MRI lesion guides the site of surgical intervention (60-90%). Patients with extratemporal MRN-E have the worst outcome (around 50% chance of seizure freedom). We studied whether electroencephalography (EEG) source imaging (ESI) of interictal epileptic activity can contribute to the identification of the epileptic focus in patients with normal MRI. METHODS: We carried out ESI in 10 operated patients with nonlesional MRI and a postsurgical follow-up of at least 1 year. Five of the 10 patients had extratemporal lobe epilepsy. Evaluation comprised surface and intracranial EEG monitoring of ictal and interictal events, structural MRI, [(18)F]fluorodeoxyglucose positron emission tomography (FDG-PET), ictal and interictal perfusion single photon emission computed tomography (SPECT) scans. Eight of the 10 patients also underwent intracranial monitoring. RESULTS: ESI correctly localized the epileptic focus within the resection margins in 8 of 10 patients, 9 of whom experienced favorable postsurgical outcomes. DISCUSSION: The results highlight the diagnostic value of ESI and encourage broadening its application to patients with MRN-E. If the surface EEG contains fairly localized spikes, ESI contributes to the presurgical decision process.

Cognition et psychopathologie chez les nonagénaires et centenaires vivant en établisement médico-social gériatrique en Suisse : focalisation sur l'anosognosie = [Cognition and psychopathology in nonagenarians and centenarians living in geriatric nursing homes in Switzerland : a focus on anosognosia]

Les nonagénaires et centenaires voient actuellement leur nombre augmenter considérablement, beaucoup d'entre eux vivant en maison de retraite. Pour cette population, on dispose de très peu de données au sujet de la Symptomatologie psychiatrique et des capacités cognitives autres que mnésiques. Cette étude exploratoire se concentre sur l'anosognosie et ses liens avec les symptômes psychiatriques et cognitifs courants. Cinquante-huit sujets âgés de 90 ans ou plus ont été recrutés dans des établissements médico-sociaux gériatriques et divisés en 5 groupes selon le Mini Mental State Examination (MMSE). Les évaluations incluent le test des 5 mots, le CLOX, les fluences lexicales et catégorielles, le questionnaire d'anosognosie- démence (AQ-D), l'inventaire neuropsychiatrique (NPI) et l'index de comorbidité de Charlson. Les sujets étudiés présentent une atteinte cognitive modérée, le MMSE moyen (±DS) étant à 15.41 ± 7.04. L'anosognosie augmente avec l'atteinte cognitive, étant associée avec tous les domaines cognitifs, mais aussi avec les symptômes psychopathologiques d'apathie et d'agitation. Les sujets ayant une atteinte cognitive légère semblent moins anosognosiques que ceux avec l'atteinte cognitive la plus faible ou ceux ne présentant aucune atteinte. Ni l'anosognosie ni les symptômes psychopathologiques ne sont liés aux comorbidités somatiques. Chez les résidents très âgés étudiés vivant en maison de retraite, l'anosognosie est principalement légère. Elle est associée à des changements cognitifs, mais aussi psychopathologiques. Des investigations supplémentaires sont toutefois nécessaires pour déterminer s'il existe un lien causal entre l'anosognosie et les atteintes psychopathologiques.

Cardiovascular disease and the changing face of global public health : a focus on low and middle income countries

Eighty percent of the global 17 million deaths due to cardiovascular disease (CVD) occur in low and middle income countries (LMICs). The burden of CVD and other noncommunicable diseases (NCDs) is expected to markedly increase because of the global aging of the population and increasing exposure to detrimental lifestyle-related risk in LMICs. Interventions to reduce four main risks related to modifiable behaviors (tobacco use, unhealthy diet, low physical activity and excess alcohol consumption) are key elements for effective primary prevention of the four main NCDs (CVD, cancer, diabetes and chronic pulmonary disease). These behaviors are best improved through structural interventions (e.g., clean air policy, taxes on cigarettes, new recipes for processed foods with reduced salt and fat, urban shaping to improve mobility, etc.). In addition, health systems in LMICs should be reoriented to deliver integrated cost-effective treatment to persons at high risk at the primary health care level. The full implementation of a small number of highly cost effective, affordable and scalable interventions ("best buys") is likely to be the necessary and sufficient ingredient for curbing NCDs in LMICs. NCDs are both a cause and a consequence of poverty. It is therefore important to frame NCD prevention and control within the broader context of social determinants and development agenda. The recent emphasis on NCDs at a number of health and economic forums (including the September 2011 High Level Meeting on NCDs at the United Nations) provides a new opportunity to move the NCD agenda forward in LMICs.

Neuronal death after perinatal cerebral hypoxia-ischemia: Focus on autophagy-mediated cell death.

Neonatal hypoxic-ischemic encephalopathy is a critical cerebral event occurring around birth with high mortality and neurological morbidity associated with long-term invalidating sequelae. In view of the great clinical importance of this condition and the lack of very efficacious neuroprotective strategies, it is urgent to better understand the different cell death mechanisms involved with the ultimate aim of developing new therapeutic approaches. The morphological features of three different cell death types can be observed in models of perinatal cerebral hypoxia-ischemia: necrotic, apoptotic and autophagic cell death. They may be combined in the same dying neuron. In the present review, we discuss the different cell death mechanisms involved in neonatal cerebral hypoxia-ischemia with a special focus on how autophagy may be involved in neuronal death, based: (1) on experimental models of perinatal hypoxia-ischemia and stroke, and (2) on the brains of human neonates who suffered from neonatal hypoxia-ischemia.

Les anticoagulants oraux directs en 2015 chez le patient âgé: focus chez le sujet fragile

Depuis les études princeps de phase III de non-inf ériorité comparant les anticoagulants oraux directs (AOD) à la warfarine, de nombreuses études ont essayé de répondre à la question de l'efficacité et de la sécurité d'utilisation des AOD chez les patients âgés. Ces études sont des études de sous-groupes complémentaires issues des études princeps ou des études de pharmacovigilance en postmarketing utilisant des données médicoéconomiques à grande échelle. De nombreux biais, par définition, peuvent entraîner une distorsion des résultats dans de telles études, rendant leur interprétation prudente. Aucun essai randomisé contrôlé n'a à ce jour comparé les AOD à la warfarine chez des patients de 80 ans ou plus et a fortiori chez des sujets âgés fragiles. En pratique, chez le patient âgé fragile, il n'y a pas de consensus quant au choix des anticoagulants à prescrire en cas de fibrillation atriale (FA) et de la maladie thromboembolique veineuse (MTEV). Quant au choix de l'AOD à privilégier chez le sujet âgé, faute d'études de comparaison directe disponibles à ce jour, il apparaît difficile de se prononcer. Toutefois, les données disponibles, tant sur le plan pharmacologique que celles issues des études complémentaires, semblent montrer que le dabigatran offre un profil bénéfice/risque moins favorable que les autres AOD. Néanmoins, les résultats prometteurs de l'idarucizumab, antidote du dabigatran, pourraient contribuer à améliorer ce rapport à l'avenir.

Modulation of the glutamatergic transmission by Dopamine: a focus on Parkinson, Huntington and Addiction diseases.

Dopamine (DA) plays a major role in motor and cognitive functions as well as in reward processing by regulating glutamatergic inputs. In particular in the striatum the release of DA rapidly influences synaptic transmission modulating both AMPA and NMDA receptors. Several neurodegenerative and neuropsychiatric disorders, including Parkinson, Huntington and addiction-related diseases, manifest a dysregulation of glutamate and DA signaling. Here, we will focus our attention on the mechanisms underlying the modulation of the glutamatergic transmission by DA in striatal circuits.

European cancer mortality predictions for the year 2016 with focus on leukemias.

BACKGROUND: Current cancer mortality statistics are important for public health decision making and resource allocation. Age standardized rates and numbers of deaths are predicted for 2016 in the European Union. PATIENTS AND METHODS: Population and death certification data for stomach, colorectum, pancreas, lung, breast, uterus, prostate, leukemia and total cancers were obtained from the World Health Organisation database and Eurostat. Figures were derived for the EU, France, Germany, Italy, Poland, Spain and the UK. Projected numbers of deaths by age group were obtained for 2016 by linear regression on estimated numbers of deaths over the most recent time period identified by a joinpoint regression model. RESULTS: Projected total cancer mortality trends for 2016 in the EU are favourable in both sexes with rates of 133.5/100,000 men and 85.2/100,000 women (8% and 3% falls since 2011, due to population ageing) corresponding to 753,600 and 605,900 deaths in men and women for a total number of 1,359,500 projected cancer deaths (+3% compared to 2011). In men lung, colorectal and prostate cancer fell 11%, 5% and 8% since 2011. Breast and colorectal cancer trends in women are favourable (8% and 7% falls, respectively), but lung and Pancreatic cancer rates rose 5% and 4% since 2011 reaching rates of 14.4 and 5.6/100,000 women. Leukemia shows favourable projected mortality for both sexes and all age groups with stronger falls in the younger age groups, rates are 4.0/100,000 men and 2.5/100,000 women, with respectively falls of 14% and 12%. CONCLUSION: The 2016 predictions for EU cancer mortality confirm the favourable trends in rates particularly for men. Lung cancer is likely to remain the leading site for female cancer rates. Continuing falls in mortality, larger in children and young adults, are predicted in leukemia, essentially due to advancements in management and therapy, and their subsequent adoption across Europe.
