The effectiveness of adding cognitive behavioural therapy aimed at changing lifestyle to managed diabetes care for patients with type 2 diabetes: design of a randomised controlled trial

Background  

In patients with type 2 diabetes, the risk for cardiovascular disease is substantial. To achieve a more favourable risk profile, lifestyle changes on diet, physical activity and smoking status are needed. This will involve changes in behaviour, which is difficult to achieve. Cognitive behavioural therapies focussing on self-management have been shown to be effective. We have developed an intervention combining techniques of Motivational Interviewing (MI) and Problem Solving Treatment (PST). The aim of our study is to investigate if adding a combined behavioural intervention to managed care, is effective in achieving changes in lifestyle and cardiovascular risk profile.     

Hypothyroidism in children with filter paper TSH of 30 to 50 microU/ml at initial screening. Implication of the TSH cut-off point for recalling of infants at risk

In a systematic screening of newborns in France during the period from 1979 to 1983, 959 infants with hypothyroidism were detected. In 16 cases of confirmed hypothyroidism the initial filter paper TSH (FP-TSH) was between 30 and 50 microU/ml. These cases emphasize the necessity of keeping a "security zone" for FP-TSH value between 30 and 50 microU/ml and of recalling these patients for a second test filter paper TSH.     

The effect of in-utero undernutrition on the insulin resistance syndrome

The metabolic and cardiovascular complications associated with in-utero undernutrition have been identified during the past 10 years. Reduced fetal growth is independently associated with an increased risk for the development of cardiovascular diseases, the insulin resistance syndrome and its components: hypertension, dyslipidemia, impaired glucose tolerance, and type 2 diabetes. All appear to result from the initial development of insulin resistance that seems to be a key component underlying this association. Several hypotheses have been proposed over the past 10 years to understand this unexpected association. Each of them points to either a detrimental fetal environment or genetic susceptibilities or interactions between these two components as playing a critical role in this context. The hypothesis that this association could be the consequence of genetic/environmental interactions remains at the moment the most attractive. Although the mechanism remains unclear, there is also some evidence that adipose tissue plays a role in the emergence of insulin resistance associated with in-utero undernutrition.     

Causes and consequences of elderly's agitated and aggressive behavior

Agitation and aggressiveness are frequent in the elderly and often related to dementia. As a result of the ageing of the general population this is becoming a major public health concern. No or little epidemiological data, during primary health care, about symptoms, co-morbidity, nor medical and social consequences of elderlys' disruptive behavior have been gathered or published in the French literature. Thus, in order to describe these disorders, a survey in cooperation with general practitioners (GP) was conducted. A representative sample of 212 French GP's, all with preferential geriatric activity were asked to conduct a study by including retrospectively their two most recent patients older than 65, who had exhibited agitation and/or aggressiveness. From this cross sectional study, 410 patients (female: 61%, male: 39%) were included. The mean age was 81 years (sd: 7.65). The patients suffered from change in verbal behavior (80%), verbal aggressiveness (71%), physical agitation (60%), wandering (48%), and/or physical aggressiveness (31%). The average of disruptive behavior symptoms per patient was 2.9. The symptoms appeared progressively in 81% of patients, the mean duration was two years and it was the first episode in 40% of patients. Disruptive behaviors may be explained in view of organic illness in 62% of patients (cardiovascular disease: 37%, neurologic: 12%, diabetes: 7%, dehydratation: 5%), dementia (Alzheimer disease: 20%, vascular dementia: 18%, mixed dementia: 14%). In 54% of patients disruptive behavior may be explained in view of depression: 34%, and anxiety disorder: 31%. A triggering factor was observed in 57% of cases (psychosocial stress: 39%). Somatic consequences of the symptoms were frequently identified: decrease of alimentary intake: 39%, weight loss: 27%, dehydratation: 11%, falls: 32%, and irregular medication intake: 31%. Limitation of daily life activities: 85%, and family life: 97% were also noted. Acceptability of patient's symptoms by the family was good (no discomfort or transitory and mild irritability) in 61% of cases, and very bad (reactions of exhaustion, hospitalization requirement) in 13%. This study carried out during primary care, showed that the elderly's disruptive behaviors cause severe medical consequences and familial and social distress.
