IMPORTANCE OF RISK ASSESSMENT: The prevention of cardiovascular disease is a major public health goal. Cardiovascular diseases are the number one cause of mortality in industrialized countries and account for an important part of health care expenditures. In this context, assessment of the cardiovascular risk for a given subject based on epidemiological data and individual risk factors can be used to determine his/her risk of ischemic heart disease or stroke. THE FRAMINGHAM FORMULA: The most widely used assessment method is the Framingham formula which integrates age, sex, blood pressure, smoking habits and presence or not of diabetes. This formula gives an objective, reproducible estimation of the cardiovascular risk and is a useful tool for therapeutic rationale and primary and secondary prevention. INTEREST AND LIMITATIONS: This new global approach to the individual patient has interesting practical and economic implications but remains imperfect due to certain limitations (other risk factors not taken into account because they are difficult to quantify or occurred recently). For daily practice however, it provides a useful tool appreciated by clinicians and patients.

THE RELIEF OF THE RESULTS OF THE HOPE TRIAL WITH RESPECT TO THE INCIDENCE OF CEREBROVASCULAR EVENT UNDER ACE INHIBITOR THERAPY: In 1998, the CAPP trial had raised a serious concern about whether captopril therapy increased the risk of cerebrovascular accidents. When compared with betablocker therapy (+/- diuretics) in 11,000 hypertensives, there was a very worrying number of excess cerebrovascular accidents in the captopril group (+25%) (with no difference in the number of cerebrovascular accidents overall). There were several reasons which led to believe that the captopril was not the causal factor. But a doubt remained. In 1999, the results of the HOPE trial with ramipril, though not primarily for a hypertensive population, provided reassurance beyond the investigators' hopes concerning the value of ACE inhibitors in the prevention of vascular events, including cerebrovascular accidents. THE FRAMINGHAM EXPERIENCE OF LVH AND THE TREATMENT OF HYPERTENSION: The Framingham study reported unique data concerning the effects of antihypertensive therapy on LVH in 10,333 subjects of 45 to 74 years of age followed up for 40 years (1950-1989). As the incidence of antihypertensive therapy increased during the observation period, that of hypertension and LVH decreased in parallel. Although these data were retrospective, they are compatible with a causal relationship between the treatment and regression of LVH. This could explain up to 50% of the decrease in cardiovascular mortality observed in the United States during this period. The Framingham study so reposition, in an epidemiological context, the considerable benefits of antihypertensive therapy and of the regression of the associated LVH. THE SEVERITY OF THE WHO AND IHS RECOMMENDATIONS: Less than 130/85: this is the target value of the blood pressure in adults under antihypertensive therapy according to WHO and IHS. In patients with diabetes or renal failure with proteinuria > 1 g/j, the target is even lower. These recommendations incite physicians to beware of any laxness in the treatment of hypertension. The most recent epidemiological data from France indicates that only a minority of the hypertensive patients under treatment are well controlled and that this advice is probably not superfluous. Moreover, in the decision to treat hypertension (drug therapy or not), these recommendations underline the evaluation of the individual risk of the subject on the basis of associated risk factors, target organ complications and previous history of vascular events.

FORMATION OF THE QUIC: The Quality Interagency Coordination Task Force (QuIC) was established in 1998 to enable the participating federal agencies to coordinate their activities to study, measure, and improve the quality of care delivered by federal health programs; provide people with information to help them in making more informed choices about their care; and develop the research base and infrastructure needed to improve the health care system, including knowledgeable and empowered workers, well-designed systems of care, and useful information systems. STUDY, MEASURE, AND IMPROVE CARE: The QuIC's initial efforts to improve the care delivered in federal health care programs have focused on diabetes, depression, and the effect of working conditions on quality of care. More recently, patient safety efforts are under way to establish a coordinating center that will enable those who are testing methods of reducing errors to share information across their projects and with experts in error reduction. DEVELOP A RESEARCH BASE AND INFRASTRUCTURE: The QuIC has coordinated efforts in credentialing, information on measures of quality, a taxonomy of quality improvement methods, and errors data collection. PROVIDE INFORMATION TO AMERICANS ABOUT HEALTH CARE QUALITY: The QuIC agencies are developing products that will enhance their ability to communicate with the American people about their health care choices: improved gateways for consumer information available from federal agencies, a glossary of commonly used terms, and guidance for producing report cards on quality of care. MOVING THE QUALITY IMPROVEMENT AGENDA FORWARD: Federal efforts to improve quality of care are moving forward in a more integrated fashion on a wide number of fronts.

PURPOSE OF THE PAPER: To summarize the current health status of Kanaka Maoli (indigenous Hawaiians) with historical background, underlying factors responsible for the Kanaka Maoli health plight and recommendations. METHODS: The author reviewed the available literature and some not readily available, unpublished information. PRINCIPAL FINDINGS: Kanaka Maoli continue to have the worst health and socio­economic indicators of the various ethnic groups in their home islands of Ka Pae'aina (Hawai'i). Cardiovascular disorders, cancer, diabetes, obstructive lung disease, maternal and infant health and mental distress are the prominent maladies. Tobacco smoking, high­fat diet, alcohol drinking, hyperlipidemia and obesity are the major lifestyle risk factors. Societal factors, such as depopulation, foreign transmigration, colonial exploitation, coercive assimilation, cultural conflict and racism persist. Since 1990, Kanaka Maoli communities have established five island­wide Native Hawaiian Health Care Systems to improve availability, accessibility, and acceptability of health services to their people, but with inadequate resources. CONCLUSIONS: Under present conditions, while the future may bring some amelioration of Kanaka Maoli ill health, the price will be progressive acculturation and loss of Kanaka Maoli identity. Accordingly, recommendations include augmented revitalization of the traditional culture, effective recontrol by the Kanaka Maoli of their lives and natural resources and thus, improved total health.

DE NOVO DIABETES AND CARDIOVASCULAR RISK: Certain kidney transplant recipients who develop de novo diabetes have an unfavorable cardiovascular risk profile, comparable to patients with type 2 diabetes mellitus, with advanced age, dyslipidemia, obesity and high blood pressure. MYOCARDIAL INFARCTION IN THE PERIOPERATIVE PERIOD: Among kidney transplant recipients, those whose risk factors include male gender diabetes, age over 50 years and prior revascularization procedure for coronary artery disease have a higher risk for myocardial infarction in the perioperative period. The usefulness of anticoagulant or beta-blockers as preventive treatment for these high-risk patients remains to be determined. HYPERLIPIDEMIA: A retrospective analysis of 530 kidney transplant recipients demonstrated that a very significant proportion of those with dyslipidemia are not receiving appropriate care although their lipid profile is indicative of a high or very high cardiovascular risk. MASSIVE PROTEINURIA: An angiotensin II inhibitor, losartan, has been found to be effective against massive proteinuria (> 3.5 g/l) occurring after kidney transplantation. CALCINEURIN-INHIBITOR-INDUCED HEMOLYTIC UREMIA SYNDROME: Five to ten percent of patients given calcineurin inhibitors develop a hemolytic uremia syndrome. Sirolimus appears to be a very interesting alternative for immunoprophylaxys against acute rejection.

BACKGROUND: Several studies have found that depressive complaints are associated with limitations in functioning that are at least comparable with those of chronic medical conditions, such as diabetes or lung diseases. However, the consequences of these associations for the utilization of general health care services are not known, certainly not for health care settings outside the United States. AIMS OF THE STUDY: To investigate the association of depressive complaints with functioning and health care utilization, comparing this with the association of chronic medical conditions with functioning and health care utilization. METHODS: In a community-based sample of Dutch adults (N=9428), chronic conditions (21 types) and depressive complaints were assessed by self-report. Only active conditions and depressive complaints, for which treatment was taking place, were selected for the analyses. Health status and disabilities were also assessed by self-report. Information on the utilization of health care services was based on self-report as well as on data extracted from a claims database. This database also provided information on the use of psychoactive medications. The associations between chronic conditions, depressive complaints and dependent variables were determined by analysis of variance or regression analysis, adjusting for possibly confounding factors (gender, age, living conditions). RESULTS: Depressive complaints, more than any chronic condition (except back problems), were associated with fatigue, poor subjective health and days spent in bed. Those having depressive complaints visited their general practitioner (GP) more often than the others. They also contacted a medical specialist more often than other patient categories, apart from patients with heart diseases. The combination of depressive complaints and chronic medical conditions was not associated with increased utilization or lower functioning. CONCLUSION: Depressive complaints are not only connected to functioning, but also to the utilization of general health care services. The strength of these associations is comparable with that of chronic medical conditions. This study stresses the pertinence of (research on) the management and treatment of patients with depressive complaints in general health care settings.

THE IMPORTANCE OF VISUAL FUNCTION IN THE ASSESSMENT OF QUALITY OF LIFE: The notion of visual function is related to visual acuity but also to many other parameters such as the visual field, perception of colour, contrasts, and the resistance to blinding. These factors are difficult to measure during routine ophthalmic examination but can be assessed during questionnaires on quality of life. MARKERS OF QUALITY OF LIFE IN OPHTHALMOLOGY: Various quality of life questionnaires have been developed in ophthalmology because the non-specific generic instruments appear inadequate. The SF 36 and SF 20 scales, which are generic instruments widely used in many fields, do not adequately explore the problems related to vision. The first efficient instrument is the VF 14, which is a questionnaire specific to ophthalmic diseases, developed by C. Mangione in 1992. This self-administered questionnaire permits calculation of a 0 to 100 score exploring 5 dimensions (long-sight acuity, near-sight acuity, unclear sight, and driving during the day and at night) during 14 activities with 18 questions. It was translated and adapted into French by Gresset in 1997. Today it is the most commonly used questionnaire in ophthalmology, particularly in the assessment of efficacy and impact in surgery. Along the other specific questionnaires developed, there is the NEI-VQF which was created in 1995 to assess vision and the impact of visual problems on the quality of life of patients, independently of an ophthalmic pathology. Many studies have been conducted on various diseases that affect vision, such as diabetes or hypertension. THE LIMITS OF EXISTING INSTRUMENTS: The specific scales appear far more sensitive and specific than generic scales with regard to ophthalmic problems, but they provide less information on the general status of the patient, except for the NEI-VQF. They are limited in some parameters and do not, unfortunately, take into account the patient's age. No specific scale has been developed for children or adolescents, although the impact of vision on daily life is fundamental. The complexity of vision means that the elaboration of an ideal instrument is difficult. However, in the meantime, it is essential that the practitioners continue to use and to test the instruments available in order to improve with regard to pathologies, or in particular sub-groups of the population.

SEVERAL MECHANISMS: The progression in renal failure first implies hemodynamic mechanisms and among which angiotensin II has a central role, but also an increase in proteinuria and the induction of many inflammatory and mitogenic mediators that enhance fibrosis (TGF-beta), an effect stimulating the thrombotic mechanism. Among these factors of progression in renal failure, hypertension and proteinuria are the two major factors. Proteinuria is "nephrotoxic" and leads to glomerular and tubulo-interstitial lesions. THE ROLE OF ANGIOTENSIN-CONVERTING ENZYME INHIBITORS: Angiotensin-converting enzyme inhibitors (ACE) affect the different mechanisms that lead to glomerulosclerosis: antihypertensive effect, with the normalisation of blood pressure having demonstrated its determining role in the production of nephrosis in various epidemiological studies; hemodynamic effect with a decrease in glomerular capillary pressure, in the filtration fraction, and inhibition of the bradykinin deterioration; antiproteinuric effect superior to that of other anti-hypertensive drugs (excepting angiotensin II-receptor antagonists). Two indications ACE inhibitors have demonstrated their efficacy in slowing the progression of renal failure in two large pathological fields: diabetic nephropathy in which this effect is demonstrated in type I diabetes, although the results are not as obvious in type II diabetes in which the nephropathy is multi-factor. The recent French and American recommendations are that ACE inhibitors should be used in first intention in diabetic nephropathies and aimed at tight blood pressure control; non-diabetic nephropathies Two pivotal studies have demonstrated the efficacy of ACE inhibitors in nephropathies whatever their type. These data have led to propose ACE inhibitors in first intention in patients exhibiting chronic nephropathies, whether hypertensive or not THE COMBINATION WITH OTHER HYPERTENSIVE DRUGS: Calcium channel blockers have a beneficial trophic effect in renoprotection and can be combined with ACE inhibitors, particularly in the case of diabetic nephropathies. ACE inhibitors and angiotensin II-receptor antagonists have comparable effect on hemodynamics and glomerulosclerosis factors. Clinically, the decrease in proteinuria is identical. Endothelin antagonists have also been studied in renoprotection and appear to have a beneficial effect when combined with ACE inhibitors. GLOBALLY: ACE inhibitors remain the only treatment with demonstrated long-term efficacy in the progression of chronic renal failure. However, the concept of renoprotection needs to be widened to all the factors implied in the progression of chronic renal failure, and ACE inhibitors only represent one aspect of treatment. The role of angiotensin II-receptor antagonists, alone or combined, is clearly promising.

Our aim is to summarize and discuss the recent literature linking diabetes mellitus with heart failure, and to address the issue of the optimal treatment for diabetic patients with heart failure. THE STUDIES LINKING DIABETES MELLITUS (DM) WITH HEART FAILURE (HF) : The prevalence of diabetes mellitus in heart failure populations is close to 20% compared with 4 to 6% in control populations. Epidemiological studies have demonstrated an increased risk of heart failure in diabetics; moreover, in diabetic populations, poor glycemic control has been associated with an increased risk of heart failure. Various mechanisms may link diabetes mellitus to heart failure: firstly, associated comorbidities such as hypertension may play a role; secondly, diabetes accelerates the development of coronary atherosclerosis; thirdly, experimental and clinical studies support the existence of a specific diabetic cardiomyopathy related to microangiopathy, metabolic factors or myocardial fibrosis. Subgroup analyses of randomized trials demonstrate that diabetes is also an important prognostic factor in heart failure. In addition, it has been suggested that the deleterious impact of diabetes may be especially marked in patients with ischemic cardiomyopathy. TREATMENT OF HEART FAILURE IN DIABETIC PATIENTS : The knowledge of the diabetic status may help to define the optimal therapeutic strategy for heart failure patients. Cornerstone treatments such as ACE inhibitors or beta-blockers appear to be uniformly beneficial in diabetic and non diabetic populations. However, in ischemic cardiomyopathy, the choice of the revascularization technique may differ according to diabetic status. Finally, clinical studies are needed to determine whether improved metabolic control might favorably influence the outcome of diabetic heart failure patients.

TWO TYPES OF SITUATIONS: Measurement of transaminase serum activity is a common biological test. Although the etiological scope of acute and severe hyper-aminotransferase is codified and limited, that of prolonged and moderate hyper-aminotransferase is much broader. IN THE CASE OF PROLONGED AND MODERATE INCREASE IN TRANSAMINASE SERUM ACTIVITY: The discovery of this abnormality during systematic biological controls is a frequent situation, and its management is relatively well standardised. It requires a rigorous diagnostic strategy, which includes the search for consumption of alcohol, overweight, chronic hepatic disease of viral origin and the nature of the medicinal products ingested. FROM AN ETIOLOGICAL POINT OF VIEW: The most frequent causes of moderate and prolonged hyper-aminotransferase are alcohol abuse, overweight, non-insulin-dependent diabetes, dyslipaemia, viral hepatitis and medicinal products. However, less frequent hepatic or extra-hepatic causes must not be neglected.
