Prevalence, awareness, treatment and control of hypertension in a Swiss general population: the CoLaus Study

Objective: To assess the prevalence levels of awareness, treatment and control of hypertension and associated factors in Switzerland. Methods: Population-based cross-sectional study of 6,182 subjects (52.5% women) aged 35-75 years living in Lausanne, Switzerland. Hypertension was defined as blood pressure ≥140/90 mm Hg or current antihypertensive medication. Results: The overall prevalence of hypertension was 36% (95% CI: 35-38%). Among hypertensive participants, 63% were aware of having hypertension. Among aware hypertensives, 78% were treated, and among treated hypertensives 48% were controlled (BP <140/90 mmHg). In multivariate analysis, prevalence of hypertension was associated with older age, male gender, low educational level, high alcohol intake, awareness of diabetes, awareness of dyslipidaemia, obesity and parental history of myocardial infarction (MI). Awareness of hypertension was associated with older age, female gender, awareness of diabetes, awareness of dyslipidaemia, obesity and parental history of MI. Control was associated with younger age, higher educational level and no alcohol intake. Alone or in combination, sartans were the most often prescribed antihypertensive medication category (41%), followed by diuretics, beta-blockers, ACE inhibitors and calcium channel blockers. Only 31% of treated hypertensives were taking ≥2 antihypertensive medications. Conclusion: Although more than half of the participants with hypertension were aware of being hypertensive and more than three quarters of them received a pharmacological treatment, less than half of those treated were adequately controlled. Treated hypertensive subjects should be followed up more closely.

Neural activity of the anterior insula in emotional processing depends on the individuals' emotional susceptibility

Differences in personality factors between individuals may manifest themselves with different patterns of neural activity while individuals process stimuli with emotional content. We attempted to verify this hypothesis by investigating emotional susceptibility (ES), a specific emotional trait of the human personality defined as the tendency to "experience feelings of discomfort, helplessness, inadequacy and vulnerability" after exposure to stimuli with emotional valence. By administering a questionnaire evaluating the individuals' ES, we selected two groups of participants with high and low ES respectively. Then, we used functional magnetic resonance imaging to investigate differences between the groups in the neural activity involved while they were processing emotional stimuli in an explicit (focusing on the content of the stimuli) or an incidental (focusing on spatial features of the stimuli, irrespectively of their content) way. The results showed a selective difference in brain activity between groups only in the explicit processing of the emotional stimuli: bilateral activity of the anterior insula was present in subjects with high ES but not in subjects with low ES. This difference in neural activity within the anterior insula proved to be purely functional since no brain morphological differences were found between groups, as assessed by a voxel-based morphometry analysis. Although the role of the anterior insula in the processing of contexts perceived as emotionally salient is well established, the present study provides the first evidence of a modulation of the insular activity depending on the individuals' ES trait of personality.

Emotional reactivity at 12 months in very preterm infants born at <29 weeks of gestation.

The present study evaluated the socio-emotional development of very preterm born infants at 12 months corrected age. Forty-one infants born very preterm (<29 weeks of gestation) were compared to 22 infants born full term on a standardized behavioral assessment and a parental temperament questionnaire, both measuring emotional reactivity to joy, anger and fear, as well as sustained attention. The behavioral assessment showed that very preterm infants exhibited as much joy as full term infants during a joy-eliciting episode. However, they expressed a significantly higher reactivity in anger-eliciting situations and a reduced reactivity toward fear-eliciting situations. For all three emotion-eliciting situations, the preterm infants reacted with a higher level of motor activity. The preterm infants also exhibited a distinct attention pattern with a significantly higher initial attention level which declined rapidly throughout the episode. The questionnaire did not show any group differences. The clinical relevance of these results in terms of preliminary hallmarks of later behavioral difficulties such attention deficit/hyperactivity disorder are discussed as well as the inconsistencies observed between the questionnaire and the behavioral assessment.

An exploratory study on facial emotion recognition capacity in beginning Alzheimer's disease.

Objective: It was the aim of this study to investigate facial emotion recognition (FER) in the elderly with cognitive impairment. Method: Twelve patients with Alzheimer's disease (AD) and 12 healthy control subjects were asked to name dynamic or static pictures of basic facial emotions using the Multimodal Emotion Recognition Test and to assess the degree of their difficulty in the recognition task, while their electrodermal conductance was registered as an unconscious processing measure. Results: AD patients had lower objective recognition performances for disgust and fear, but only disgust was accompanied by decreased subjective FER in AD patients. The electrodermal response was similar in all groups. No significant effect of dynamic versus static emotion presentation on FER was found. Conclusion: Selective impairment in recognizing facial expressions of disgust and fear may indicate a nonlinear decline in FER capacity with increasing cognitive impairment and result from progressive though specific damage to neural structures engaged in emotional processing and facial emotion identification. Although our results suggest unchanged unconscious FER processing with increasing cognitive impairment, further investigations on unconscious FER and self-awareness of FER capacity in neurodegenerative disorders are required.

Emotional behavior in acute stroke: the Lausanne emotion in stroke study.

OBJECTIVE: To study emotional behaviors in an acute stroke population. BACKGROUND: Alterations in emotional behavior after stroke have been recently recognized, but little attention has been paid to these changes in the very acute phase of stroke. METHODS: Adult patients presenting with acute stroke were prospectively recruited and studied. We validated the Emotional Behavior Index (EBI), a 38-item scale designed to evaluate behavioral aspects of sadness, aggressiveness, disinhibition, adaptation, passivity, indifference, and denial. Clinical, historical, and imaging (computed tomography/magnetic resonance imaging) data were obtained on each subject through our Stroke Registry. Statistical analysis was performed with both univariate and multivariate tests. RESULTS: Of the 254 patients, 40% showed sadness, 49% passivity, 17% aggressiveness, 53% indifference, 76% disinhibition, 18% lack of adaptation, and 44% denial reactions. Several significant correlations were identified. Sadness was correlated with a personal history of alcohol abuse (r = P < 0.037), female gender (r = P < 0.028), and hemorrhagic nature of the stroke (r = P < 0.063). Aggressiveness was correlated with a personal history of depression (r = P < 0.046) and hemorrhage (r = P < 0.06). Denial was correlated with male gender (r = P < 0.035) and hemorrhagic lesions (r = P < 0.05). Emotional behavior did not correlate with either neurologic impairment or lesion localization, but there was an association between hemorrhage and aggressive behavior (P < 0.001), lack of adaptation (r = P < 0.015), indifference (r = P < 0.018), and denial (r = P < 0.045). CONCLUSIONS: Systematic observations of acute emotional behaviors after stroke suggest that emotional alterations are independent of mood and physical status and should be considered as a separate consequence of stroke.

Schistosomiasis mansoni in Bananal (State of São Paulo, Brazil): IV. Study on the public awareness of its risks in the Palha District

A rather high prevalence of mansoni schistosomiasis has been observed in some localities of Bananal, State of São Paulo, during the past decade. The highest prevalence of schistosomiasis was found in the Palha District; it was thus considered adequate for an evaluation of public awareness of the risks involved in acquiring schistosomiasis, a likely outcome of certain behavior patterns. We interviewed 542 district-dwellers. The 5-to-39 age-group constituted 65.5% of the whole sample. Concerning the infection, 69.2% had hearsay information; 46.1% know the infection; 69.6% know how it is acquired; 31.5% know about the symptoms and 57.1% know what can be done to avoid infection; 17.7% declared to have acquired the infection at least once in their lifetime; 62.3% reported total or partial immersion in collections of water of Bananal, once or twice a week, 53.9% of these for bathing or fishing. Although most (91.7%) households have treated running water, are connected to the sewage network or have septic tanks, 9% of the people interviewed use to defecate on the field. It became clear that the educational messages aimed at this population had not been adequate, having failed to fulfil any expectations. The local people received only piecemeal and subjective information about their problem. The control of schistosomiasis requires an integrated practice, which includes the analysis of macro-determinant factors, such as basic sanitation, habitation, education and health care. In short, we require a multidisciplinary vision of the mechanisms of transmission of the infection, which depends upon adequate planning and well trained personnel, intent on their educational work, to attain satisfactory results.

PHA reinforce sensible drinking in Alcohol Awareness Week

Recent health figures show that 20% of adults surveyed admitted to drinking over the weekly alcohol limits (1)so the Public Health Agency is using Alcohol Awareness Week (14-20th November) to reinforce the importance of drinking sensibly and staying within safe alcohol limits.Government guidelines on safe drinking are 21 units per week for males and 14 units per week for females. Staying within these limits is important as excessive and binge drinking can lead, in the short term, to increased risk of accidents, antisocial behaviour, impact on relationships, unplanned pregnancy. Longer term it can damage the liver, heart, brain and stomach, not to mention the other human costs, and costs to the economy and society as a whole.Owen O'Neill, PHA Health and Social Wellbeing Improvement Manager and Drugs and Alcohol Lead, said: "The Department of Health, Social Services and Public Safety's drinking limits are in place to encourage the public to develop safe and sensible drinking habits. However, these recent figures highlight that not everyone is adhering to these limits. It is crucial that those who do decide to have a drink do so in moderation and stick to the recommended limits to prevent any long or short term damages".The message is clear, if you drink, remember to be smart and enjoy alcohol within safe limits. People should follow the recommended daily alcohol intake. These are:Men: No more than 3 to 4 units of alcohol a day and no more than 21 units over the course of the week.Women: No more than 2 to 3 units of alcohol a day and no more than 14 units over the course of the week.Examples of units:Can of extra strong lager - 4 unitsBottle of lager - 1.5 unitsPint of standard lager - 2.5 unitsPint of premium larger - 3 unitsSmall pub bottle of wine - 2.25 unitsPub measure of spirits - 1.5 unitsPint of cider - 3 unitsPint of stout - 2.5 units. Remember, that for each unit you drink over the daily limit, the risk to your health increases. It's important to spread the units throughout the week - you can't 'save up' your units for the weekend or an upcoming holiday. It is also important to drink plenty of water, ideally matching the amount of alcohol you have consumed.For further information on sensible drinking and alcohol units visit the Public Health Agency's website www.knowyourlimits.infoReference(1) Health Survey Northern Ireland: first results from the 2010/2011 survey (2011) DHSSPS, http://dhsspsni.giv/index/stats_research/stats-public-health.htm
