RESUMO

BACKGROUND AND PURPOSE: The incidence and prevalence of Parkinson's disease are important for public health planning yet there is a lack of representative, up-to-date estimations for France. METHODS: For this cross-sectional study, subjects with suspected Parkinson's were identified in the EGB database, a 1/97 random sample of the national healthcare insurance database, linked to the national hospital-discharge summary database. Incidence and prevalence were estimated using a specific definition that included those with a diagnosis (hospitalization or listed as a long-term chronic disease for full reimbursement) and a sensitive definition that also included those with an indicative drug reimbursement profile. Estimations were extrapolated to the national population, standardizing on age and gender. RESULTS: According to either the specific or the sensitive definitions, the annual incidence of Parkinson's disease during the study period was respectively 36 and 49 per 100,000 person-years and prevalence in 2010 was 308-410 per 100,000 persons in the population as a whole. According to the age groups 55-64, 65-74, 75-84 and ≥85 years incidence was respectively 33-46, 139-172, 301-363 and 442-560 per 100,000 person-years amongst men and 32-55, 81-117, 203-270 and 251-313 per 100,000 person-years amongst women. The 2010 prevalence stratified by the same age groups was 293-376, 898-1161, 2524-3011 and 3760-4578 per 100,000 persons amongst men and 199-351, 618-889, 1910-2433 and 2504-3263 per 100,000 persons amongst women. CONCLUSIONS: The specific and sensitive definitions of disease bracket the true values; the relatively small range indicates that the current study provides good estimations of incidence and prevalence of Parkinson's disease for recent years in France.

RESUMO

AIMS/HYPOTHESIS: Using the Echantillon Généraliste de Bénéficiaires: random 1/97 permanent sample of the French national healthcare insurance system database (EGB), we investigated whether, as previously suspected, the risk of cancer in insulin glargine (A21Gly,B31Arg,B32Arg human insulin) users is higher than in human insulin users. The investigation period was from 1 January 2003 to 30 June 2010. METHODS: We used Cox proportional hazards time-dependent models that were stratified on propensity score quartiles for use of insulin glargine vs human insulin, and adjusted for insulin, biguanide and sulfonylurea possession rates to assess the risk of cancer or death in all or incident exclusive or predominant (≥ 80% use time) users of insulin glargine compared with equivalent human insulin users. RESULTS: Only type 2 diabetic patients were studied. Exposure rates varied from 2,273 and 614 patient-years for incident exclusive users of insulin glargine or human insulin, respectively, to 3125 and 2341 patient-years for all patients predominantly using insulin glargine or human insulin, respectively. All-type cancer HRs with insulin glargine vs human insulin ranged from 0.59 (95% CI 0.28, 1.25) in incident exclusive users to 0.58 (95% CI 0.34, 1.01) in all predominant users. Cancer risk increased with exposure to insulin or sulfonylureas in these patients. Adjusted HRs for death or cancer associated with insulin glargine compared with human insulin ranged from 0.58 (95% CI 0.32, 1.06) to 0.56 (95% CI 0.36, 0.87). CONCLUSIONS/INTERPRETATION: There was no excess risk of cancer in type 2 diabetic patients on insulin glargine alone compared with those on human insulin alone. The overall risk of death or cancer in patients on insulin glargine was about half that of patients on human insulin, thereby excluding a competitive risk bias.

RESUMO

AIM: One of the aims of the TEMPPO study was to describe the sociodemographic and clinical characteristics of a cohort of adult outpatients with type I or type II bipolar disorders (as defined by DSM-IV criteria) in France. METHODS: TEMPPO is a multicenter, cross-sectional, non-interventional study conducted in France between November 2008 and May 2009, with a random sample of academic and private practice psychiatrists. Each psychiatrist who agreed to participate in the study had to: complete a register with data on all consecutive patients (up to 20 patients) consulting during a 2-month period and fulfilling inclusion criteria; include in the study the first five patients of the register with an on-going consultation for at least 6 months; for each of which a detailed questionnaire had been assessed, notably their sociodemographic and bipolar clinical characteristics. Adult outpatients diagnosed with bipolar disorders (BD) were enrolled if fulfilling the following inclusion criteria: man or woman, aged 18 and above, diagnosed bipolar type I or II according to DSM-IV criteria, treated (whatever the treatment strategy) or not, and followed-up for at least 6 months by the participating psychiatrist. RESULTS: One hundred and thirty-five psychiatrists included 619 patients with bipolar disorder (197 and 422 followed-up in public and private practice respectively). The estimated prevalence of patients with bipolar disorders consulting psychiatrists was 0.43%. Type I bipolar disorder was the most frequent condition (58% of the patients). As a whole, bipolar disorder was associated with severe handicap (mean global disease Clinical Global Impression [CGI]-Severity score of 4.4 and mean GAF [Global Assessment of Functioning] score of 59), with more depressive episodes than manic episodes (6 vs. 4) or hypomania (6 vs. 3), a high proportion of rapid cycles (11%), psychiatric comorbidities (45% of patients), obesity (16% of patients), libido dysfunction and associated psychotic symptoms. Current manic phase was associated with more pronounced illness severity and lowest functioning. More than half of the patients (57%) had a family history of psychiatric disorders. CONCLUSION: This study could shed some light for a better understanding of demographics and clinical patterns of patients with bipolar disorders consulting psychiatrists in France. The results emphasize the severity of bipolar disorders with mainly depressive episodes, a high proportion of rapid-cycling, comorbidities and associated psychotic symptoms; these characteristics being more marked in patients suffering from BD I. Furthermore, this study confirms the strong negative impact on social and professional life of French bipolar patients, requiring specific management in addition to the symptomatic treatment.

RESUMO

TEMPPO is an observational, cross-sectional and multicentre study, initiated in the French metropolitan territory in 2009. Set up from a random sample of 135 psychiatrists, it has observed the procedures for therapeutic management of a population (n=619) of their outpatients (respectively 197 and 422 in public and private practice) with bipolar disorder type I or II disorders (DSM-IV). The patients who were followed were mostly very sick. Every patient received a pharmacological treatment. The prescription included at least one mood stabilizer or an antipsychotic (71 % atypical) in 78 % and 56 % of cases respectively. Treatment regimen changes were frequent (61 % of patients had at least one change in treatment during the last 12 months). A single molecule by therapeutic class was generally prescribed. The presence of an antipsychotic in combination therapy was often associated with the severity or difficulty of care of the patient (mixed states, severity of the global functioning impairment, manic states, high number of hospitalizations and history of suicide attempt). The combination of two antipsychotics is found only in the difficult situations of manic states. Patients with severe depressive phase are those who benefit from the combination mood stabilizer+antipsychotic+antidepressant (16 % of the sample). In this study, the prescription of antidepressants significantly differs from recommendations for good prescribing practices. Indeed antidepressants were commonly prescribed in mixed-phase (63 %), particularly as a monotherapy in 5 % of cases. It was also found in patients in euthymic phase (48 %), manic phase (12 %) and hypomanic phase (29 %). The prescription of atypical antipsychotics (monotherapy or combination) is now fully established in the management of all phases of the disease. The importance of non-pharmacological treatment is acknowledged by psychiatrists and proposed whether a psychotherapeutic support, information about the disease and/or lifestyle changes. The data collected in this study allowed to demonstrate that the participant psychiatrists have a pharmacological management of patients with bipolar disorder mostly in line with national and international guidelines.

RESUMO

OBJECTIVE: To estimate the costs of healthcare resource consumption in the year preceding and the year following a myocardial infarction (MI). PATIENTS AND METHODS: A historical cohort of patients experiencing an MI in France between 2007 and 2011 was extracted from the échantillon généraliste de bénéficiaires, a 1/97th sample of all beneficiaries of public health insurance in France. RESULTS: A total of 1920 patients experiencing an MI were identified. Two-thirds were men and the mean age was 67 years; 20.6% had diabetes, 37.6% hypercholesterolaemia and 82.4% hypertension. From a societal perspective, the annual costs of medical consumption related to hospitalisations increased from € 4548 before the MI to € 6470 in the following year. Costs of community care rose from € 2932 to € 6208. This increase concerned all components of community healthcare: costs associated with medical transportation increased fourfold, those associated with consultations and laboratory tests tripled, medication costs doubled and costs of paramedical services also increased, but to a lesser extent. It should be noted that the cost of hospitalisation for the index MI (€ 5876) is not included in the above costs. CONCLUSION: From a society perspective, the cost of healthcare resource consumption increased threefold in the year following an MI.

RESUMO

BACKGROUND: Our objective was to describe and compare neuroleptic drug utilization patterns among French schizophrenic outpatients in public and private care settings. METHODS: A cross sectional survey was carried out by a random sample of 61 public and 112 private psychiatrists who registered for one month all schizophrenic adult outpatients treated with a neuroleptic drug. Among registered patients, each psychiatrist was to include a maximum of 18 patients (public setting) or 9 patients (private setting). Statistical analysis was weighted to take into account for psychiatrist activity level, assessed by patient registration. RESULTS: Psychiatrists included 934 patients in the public care setting and 927 patients in the private care setting. Patients were (mean+/-sd) 40.1+/-12.1 years old, 60.9% men. The patients' social and clinical characteristics were less favorable in the public setting than in the private setting: no professional activity (78.9% vs 65.1%), living in institution (7.2% vs 3.7%), under legal protection (35.1% vs 14.5%), drug abuse (9.6% vs 5.6%). An atypical neuroleptic was prescribed for 63.0% of patients and a classic neuroleptic for 49.7%, an association of neuroleptics for 22.0%. In both settings, the most prescribed neuroleptics were olanzapine (28.0%) and risperidone (18.6%) with a higher mean daily dosage in the public care setting. At least one neuroleptic treatment change (drug and/or dosage) occurred during the previous year for 44.9% and 39.2% patients, in public and private settings, respectively. In both settings, reasons for changes were mainly lack of efficacy (55.1%) and side effects (49.8%). CONCLUSION: Public and private care populations were different but not as much as expected. In both settings, atypical neuroleptics were the predominant drugs used in the treatment of schizophrenia outpatients. The high frequency of drug change for lack of efficacy or side effects demonstrates the difficulties with the use of the present neuroleptic armamentarium.

RESUMO

OBJECTIVE: To compare the efficacy of the short-acting insulin analog lispro (LP) with that of regular insulin in IDDM patients treated with an external pump. RESEARCH DESIGN AND METHODS: Thirty-nine IDDM patients (age, 39.4 +/- 1.5 years; sex ratio, 22M/17W; BMI, 24.4 +/- 0.4 kg/m2; diabetes duration, 22.5 +/- 1.6 years) who were treated by external pump for 5.1 +/- 0.5 years were involved in an open-label, randomized, crossover multicenter study comparing two periods of 3 months of continuous subcutaneous insulin infusion with LP or with Actrapid HM, U-100 (ACT). Boluses were given 0-5 min (LP) or 20-30 min (ACT) before meals. Blood glucose (BG) was monitored before and after the three meals every day. RESULTS: The decrease in HbA1c was more pronounced with LP than with ACT (-0.62 +/- 0.13 vs. -0.09 +/- 0.15%, P = 0.01). BG levels were lower with LP (7.93 +/- 0.15 vs. 8.61 +/- 0.18 mmol/l, P < 0.0001), particularly postprandial BG levels (8.26 +/- 0.19 vs. 9.90 +/- 0.20 mmol/l, P < 0.0001). Standard deviations of all the BG values (3.44 +/- 0.10 vs. 3.80 +/- 0.10 mmol/l, P = 0.0001) and of postprandial BG values (3.58 +/- 0.10 vs. 3.84 +/- 0.10 mmol/l. P < 0.02) were lower with LP. The rate of hypoglycemic events defined by BG < 3.0 mmol/l did not significantly differ between LP and ACT (7.03 +/- 0.94 vs. 7.94 +/- 0.88 per month, respectively), but the rate of occurrences of very low BG, defined as BG < 2.0 mmol/l, were significantly reduced with LP (0.05 +/- 0.05 vs. 0.47 +/- 0.19 per month, P < 0.05). At the end of the study, all but two (95%) of the patients chose LP for the extension phase. CONCLUSIONS: When used in external pumps, LP provides better glycemic control and stability than regular insulin and does not increase the frequency of hypoglycemic episodes.

RESUMO

OBJECTIVE: To provide a quantitative and population-based analysis of sexual repertoires among heterosexuals. DESIGN: The French National Survey of Sexual Behaviour (ACSF), conducted between September 1991 and February 1992 on a representative sample of the population aged 18-69 years. METHODS: Sexual practices of the last heterosexual encounter were investigated among 4261 individuals; we measured the combinations of different practices and their correlations with age, and calculated frequencies for the main repertoires and their correlations with the interpartner relationship. RESULTS: Vaginal penetration and caressing were almost systematic, self-masturbation and anal penetration were rare, while mutual masturbation and orogenital practices had intermediate levels of occurrence. Examination of the correlations revealed (1) a very high correlation between practices which are reciprocal or symmetrical, (2) a strong association between genito-manual and genito-oral practices, (3) an association between anal penetration and fellatio, and (4) no clear correlation between any set of practices and vaginal sex or condom use. A small number of repertoires accounted for the vast majority of encounters. Younger people tended to have a more diversified repertoire. Repertoire types and diversity were strongly correlated to the pattern of interpartner relationship, independently of age. CONCLUSIONS: Reciprocity seems a standard feature of the heterosexual repertoire. The absence of a negative correlation between vaginal or anal penetration and other practices argues against promotion of the latter as substitute for the former. By contrast, the independence between condom use and any specific repertoire argues for its promotion as a universal means of protection.

RESUMO

To determine the extent and origin of the stimulation of 15-lipoxygenase activity in atherosclerotic aortas, formation of hydroxy-derivatives from arachidonic acid was measured by HPLC-analysis and 15-lipoxygenase mRNA expression was investigated by RNA blot and in situ hybridization in atherosclerotic and normal rabbit aortic tissues. The synthesis of hydroxy-eicosatetraenoic acids (HETE) from exogenously added [14C]arachidonic acid was unchanged in atherosclerotic aortas in comparison with healthy aortas, but pretreatment with indomethacin demonstrated that 15-HETE production resulted essentially (75%) from cyclooxygenase activity in healthy aorta and from lipoxygenase activity in atherosclerotic aorta. The RNA blot and in situ hybridization with radiolabelled oligonucleotide probe demonstrated that 15-lipoxygenase mRNA was strictly localized in intimal thickening of atherosclerotic aortas. The immunostaining using anti-alpha smooth muscle actin, revealed that smooth muscle cell rich areas of the intimal thickening expressed 15-lipoxygenase mRNA. In addition, RNA blot hybridization indicated that cultured smooth muscle cells from atherosclerotic aortas expressed strongly 15-lipoxygenase mRNA. These results demonstrate that augmentation of 15-lipoxygenase activity in atherosclerotic aortas is correlated with 15-lipoxygenase mRNA expression in atherosclerotic plaque, and that intimal smooth muscle cells were involved, in addition to macrophages, in the expression of 15-lipoxygenase.

RESUMO

The subjective response to the prescription drug zopiclone, an hypnotic agent belonging to the cyclopyrrolone family, was assessed under the usual conditions of prescription of an hypnotic in general practice. The study included 20,513 insomniac outpatients with at least two of the following symptoms: sleep onset latency longer than 1 hour, more than two nocturnal awakenings, early morning awakening 1 hour or more before scheduled time, total sleep time of less than 6 hours, complaint of tiredness on awakening. Insomniac patients were treated with zopiclone and followed for 21 consecutive days within the context of a follow-up surveillance study. The population was predominantly female (62.6%), and the mean age was 52.3 years. The dosage of zopiclone prescribed at the inclusion visit was 7.5 mg per day in 87.5% of the cases and 3.75 mg per day in 10.5%. A total of 93.8% of the patients completed the survey. Spiegel questionnaire improved during the 21-day survey, and 9.2% of the patients reported at least one adverse event that led to treatment discontinuation in only 2.8% of the population. No serious or unexpected adverse events were reported.

RESUMO

The hydroxylated derivatives of polyunsaturated fatty acids may be potent modulators of basic biological responses involved in pathological processes, including atherosclerosis. The object of the present investigation was to study the effects of monohydroxylated fatty acids (namely 12-HETE) on the properties of aortic smooth muscle cells (SMC) in culture. The changes in cell expression of differentiation antigen alpha-SM actin and 2P1A2 was followed by computerized morphometry, using specific monoclonal antibodies and the activation of cells by measuring cell motility. In addition, intracellular [Ca2+]i mobilization and IP3 formation were studied. Finally, the metabolic routes of monohydroxylated compounds and their effects on PGI2 secretion were reported. The results demonstrate that 12-HETE is able to stimulate the phenotypic modulation. PGI2 production and motility of arterial SMCs, despite any detectable activity in increasing [Ca2+]i or IP3 formation. By contrast with parent compounds 15-HETE and 13-HODE, which appear as potent prodifferentiating molecules, 12-HETE is specifically metabolized via a 10-11 reductase pathway in addition to the classical beta-oxidation pathway. Taken together, our results suggest that cellular metabolism of 12-HETE, produced by platelets in the vicinity of the arterial intima, and also by cells present inside the atherosclerotic intima, or associated with modified LDL may play a key role in the atherosclerotic process.

RESUMO

The eventuality of tolerance was assessed in 19 patients with unstable angina treated by continuous intravenous infusion of 50 micrograms/min of isosorbide trinitrate (ISDN) in association with heparin and betablocker therapy. The tolerance phenomenon was evaluated by the hypotension produced by the ISDN infusion and by the amplitude of fall in blood pressure produced by an intravenous bolus of 1 mg of glyceryl trinitrate (GTN) according to the principle of crossed tolerance to the two nitrate derivatives. Under these conditions of administration, the authors observed partial attenuation of the blood pressure response to continuous ISDN infusion and absence of cross tolerance between ISDN and intravenous GTN. The co-prescription of intravenous N-acetylcysteine at a dosage of 10 g/24 hours in 10 of the 19 patients did not affect the blood pressure or the response to the GTN bolus compared with the 9 other patients who had received placebo after double-blind randomisation. The results of this study do not indicate if the maintenance of vascular sensitivity to nitrate derivatives at least for 72 hours, was related to the choice of a relatively low dose and/or the use of ISDN rather than another nitrate derivative, in particular glyceryl trinitrate. The use of intravenous ISDN at a low dose over a 3 day period in the usual conditions of prescription for unstable angina does not seem to induce a quantitatively significant phenomenon of tolerance.

RESUMO

BACKGROUND: Since February 1996, French GPs are allowed to prescribe high dosage buprenorphine for maintenance treatment of major opioid drug addiction. A prospective cohort of major opioid addicts was initiated in order to assess patient outcomes: follow-up, retention rate in treatment, drug use, intravenous injection and social situation evolution. METHODS: Each GP, known to be involved in drug user management, had to include the first 10 opioid drug addict patients to whom he prescribed high dosage buprenorphine, with a maximum inclusion period of 3 months. Patients were followed up for two years and a regular standardized information was collected (usual data on drug users and prescription modalities). RESULTS: Between May and July 1996, 919 patients (664 men and 255 women, mean age: 30 years) were included by 101 GPs. They had a long and serious history of drug addiction, important parallel consumption of cocaine, codeine and other illicit drugs and psychiatric problems (28% of definite problems and 45% of probable) and frequent hepatic conditions (hepatitis B: 23%, hepatitis C: 21%). Two years later, 55% of patients were still followed-up by the same GP and an additional 12% were followed by another GP or in a health care service (hospitalized or receiving methadone in a specialized centre). 13% were not followed, but GPs were able to describe their situation. 8% had been included by GPs who had dropped the study. Finally, 12% of patients were lost to follow-up. Among the 508 patients still followed-up by the same GP after 2 years, the substitution treatment rate was 84%. The dosage bracket had widened (inclusion: mean dosage=7.8 mg +/-4.5, minimum=0.8, maximum=28, median=8; after 2 years: mean=7.6 mg +/-5.4, minimum=0.4, maximum=28, median=8) and the duration of the prescription and dispensing had increased. Declaration of heroin intake in the previous month had fell from 40% to 11% and declaration of drug intake from 53% to 20%. Social situation had improved on average (housing conditions and work). There were 12 seroconversions for hepatitis B, 21 for hepatitis C and 4 for HIV. 14% of patients had declared intravenous injection of high dosage buprenorphine in the previous month. CONCLUSION: After two years of follow-up, 55% of patients were still followed-up by the same GP and an additional 12% was followed by another GP or in a health care service. Among patients still followed up by the same GP, a reduction of drug related harm (seroconversions for hepatitis B, hepatitis C and HIV) was observed.

RESUMO

This study aimed to describe the short term follow-up of a cohort of 198 i.v. heroin users by 44 highly motivated General Practitioners (GPs). The study showed that for these GPs, the work-load linked with the care of these patients was heavy. Nearly half of them saw at least one drug-addict every day. These GPs work within a network and stated they benefit from a regular training on drug addiction topics. The profile of i.v. heroin users, followed by these GPs, is different from the ones usually described in other health care structures (higher percentage of women and better social insertion). The two main motives to consult a GP are the demand of drugs concerning their addiction and medical concern (due to infectious diseases especially). The answer of GPs, concerning the demand of drugs, divide physicians into two groups: those who never prescribe morphine like drugs as substitution and those who do so. In addition, both of them often prescribe psychotropic drugs to some of their patients. Nevertheless, these prescriptions are just one of the elements of a follow-up contract between a GP and his patients. Morphine like prescription is more frequently described among long term drug-addicts already well-known by GPs. This selection prohibits a straight comparison of the results of two groups of patients (with and without morphine like substitution). But the main fact is that patients under morphine like substitution are followed better (in terms of continuity) after 4 months of observation.

RESUMO

BACKGROUND: During these last years, many structured and standardized diagnostic interviews have been developed in order to identify psychiatric disorders in a standardized way. These tools enable a systematic investigation of these disorders according to international classifications. Their main drawback is to be long. To assess the care of depression, we used a shorter and more simple tool: the Mini International Neuropsychiatric Interview (MINI) to identify depressive subjects. METHOD: The study was conducted in the Gazel cohort from the French National Electricity and Gas Company. A stratified sample of 2394 civil servants selected in order to over-represent depressive subjects was asked to answer to the MINI interview through a phone interview. An epidemiological and statistical analysis was performed to test the MINI internal validity: prevalence of depressive disorders using different threshold of diagnosis (number of symptoms required to identify someone as depressive), frequency of different symptoms, variability between investigators and potential biases. RESULTS: Respondents to the phone interview (1108 civil servants) had more often presented depression markers for the last 5 years. Prevalence of depressive episodes changed little when we varied the threshold of diagnosis and did not stress any threshold problem. The variability between investigators was important, but the estimation of prevalence remained stable when we excluded extreme rates of prevalence. The choice of a classification system affected the prevalence estimation. Using the Diagnostic and Statistical Manual of Mental Disorders (DSM IV) from the American Psychiatric Association, the prevalence of depressive episodes was lower and closer to the estimations shown in the literature than using the International Classification of Disease (ICD 10). Moreover, the stratification assigned very unbalanced weights to the stratification strata. By excluding depressive episodes observed in the stratum "control" (no depression "marker" from 1989 to 1994 in the database), the prevalence was very lower, whatever the classification was. Finally, factors which appeared linked to care of depression with the ICD definition remained the same when the DSM diagnosis definition was used, and relative risks were quite similar. CONCLUSION: The MINI appears to be a short and simple tool, suited to the epidemiological studies. This analysis does not highlight any failure in the internal consistency of the MINI. The remaining question is what the MINI really measures, particularly comparing to a psychiatrist's diagnosis.

RESUMO

OBJECTIVES: To evaluate rates of continuation with hormone replacement therapy (HRT) at 2 years in 2 cohorts of female patients, one of which was treated with a set combination of oral oestradiol valerate and medroxyprogesterone acetate and the other with percutaneous 17 beta-oestradiol gel combined with an oral progestogen selected by the prescribing doctor. PATIENTS AND METHODS: A prospective, randomised, open study, including 885 patients followed for 2 years whose 477 were in the oral HRT cohort and 408 were in the dermal cohort. Randomisation was done by group with prescription of the selected HRT for the cohort. The 2 treatment groups were compared using chi(2) tests and Fisher's exact test for qualitative variables, Student's t test or Wilcoxon's test for qualitative variables and Kaplan-Meier survival curves for continuation of HRT, with comparisons using the log-rank test. The prognostic value of baseline parameters on subsequent continuation of HRT was studied using the Cox model (Wald test, odds ratio). RESULTS; Among the 885 treated patients, 711 received the HRT assigned to their cohort (382 in the oral HRT cohort, 329 in the dermal HRT cohort). After 2 years, 77.9% of the patients in the oral HRT cohort and 73.4% of the patients in the dermal HRT cohort were continuing to take their prescribed HRT (P = 0. 076): 37.9% of patients in the oral HRT cohort and 20.2% of patients in the dermal HRT cohort (P < 0.001) continued taking their treatment without any modification. CONCLUSION: Although there was no significant difference in the level of compliance in the 2 groups, it is nonetheless worth noting that the HRT compliance with a sequential fixed estroprogestogen combination was, in this trial, at least equal to that with the free combination of a transdermal estrogen and a progestogen whose nature, dosage and sequence duration are selected by the prescriber. On the other hand, treatment modifications occurred more frequently in the cutaneous HRT group, which is logical as free combination affords to adapt the treatment to each patient.

RESUMO

OBJECTIVES: Information campaigns are implemented to improve knowledge of cardiovascular disease and risk factors. The impact of these programs must be evaluated to determine whether they truly contribute to modifying risk factors in the population. METHODS: A 5-year information campaign on cardiovascular disease and risk factors was conducted in Epernon, France. The main objectives of the campaign focused on stopping smoking, regular physical exercise and balanced nutrition. Data were collected from a representative sample of the female and male population aged 20 to 65 years selected from the study town Epernon (500 subjects), and in control towns, Magny-en-Vexin and Moret-sur-Loing (200 subjects). The study town and control towns were comparable for population, demographic characteristics and geographic localization (distance from Paris). The subjects were invited to respond to a questionnaire on demographic data, attitudes toward health, risk factors and diet and underwent a clinical examination with blood tests. RESULTS: The initial sample included 961 subjects and 68.5% participated in the final survey. We were unable to evidence any significant difference in risk factors or the 10-year risk score calculated from the Framingham equation adapted to France. The information campaign was well accepted, the population not expression a feeling of lassitude. The campaign had a minimal effect on the way individuals relate to health. There was a fall in mean energy intake, mainly fat calories, which was similar in all three towns. CONCLUSION: No major modification in cardiovascular risk factors was observed in this low-risk population, suggesting that future information campaigns should be aimed at targeted populations with a higher risk profile using simple and selected messages.
