Metabolic syndrome according to different definitions in a rapidly developing country of the African region

Rapport de synthèseLe syndrome métabolique représente un ensemble de facteurs de risque métaboliques souvent présents simultanément et il est associé à un risque accru de développer des maladies cardiovasculaires. La prevalence du syndrome métabolique est à la hausse au niveau mondial comme cela a souvent été documenté, en particulier dans les pays développés. Pourtant, les données concernant le syndrome métabolique dans les pays de la région sub-saharienne restent rares.Au cours des dernières années, plusieurs définitions du syndrome métabolique ont été formulées, dont celle du 'National Cholesterol Education Program Adult Treatment Panel III', celle de 1 Organisation Mondiale de la Santé et celle du 'International Diabetes Federation'. Parmi les controverses au sujet du syndrome métabolique persiste la question de l'utilité de rechercher la présence du syndrome métabolique chez les patients diabétiques, étant donné que la présence d'un diabète en soit suffit pour identifier un individu à haut risque de faire un événement cardiovasculaire.L'objectif de ce travail de thèse a été de déterminer la prévalence du syndrome métabolique selon les trois définitions majeures mentionnées ci-dessus, grâce à une étude de population transversale, réalisée aux Seychelles en 2004 dans un échantillon représentatif de la population âgée de 24-65 ans (n=1255, taux de participation de 80.3%). L'intérêt d'examiner cette question dans ce pays était d'obtenir des informations dans un pays en transition épidémiologique.Les résultats de ce travail montrent que la prévalence du syndrome métabolique aux Seychelles est élevée, quelque soit la définition utilisée. Selon la définition utilisée, cette prévalence était d'environ 25% chez les hommes et variant entre 25 et 35% chez les femmes.Cependant, malgré des prévalences semblables selon ces trois définitions, la concordance entre ces définitions n'était pas bonne, impliquant que ces différentes définitions classifient, à un certain degré, des individus différents comme étant porteurs du syndrome métabolique.En outre, la plupart (environ 80%) des individus diabétiques avaient un syndrome métabolique. Après exclusion des individus diabétiques, la prévalence du syndrome métabolique dans la population est réduite d'environ un tiers, à environ 20-25%.Ces résultats montrent que, d'une part, le fardeau de maladie dû au syndrome métabolique aux Seychelles, un pays en voie de développement, est considérable. Cette observation peut potentiellement s'appliquer à d'autres pays à un stade de développement semblable. Cela renforce le besoin de mettre en oeuvre des stratégies de santé publique afin de cibler les causes de ces désordres métaboliques, tels que le surpoids et la sédentarité. D'un point de vue du diagnostic, les trois définitions du syndrome métabolique semblent classifier un nombre semblable de personnes atteints du syndrome métabolique dans cette population. Par contre, la relativement mauvaise concordance entre ces définitions - certaines personnes identifiés comme porteurs du syndrome métabolique selon une définition ne le sont pas selon une autre - confirme la nécessité de clarifier la signification de ces différentes définitions et/ou éventuellement de développer une définition unifiée et fiable du syndrome métabolique.

09011-008 Walnut Creek Final Report

Walnut Creek is a Class B warm water stream located in northern Poweshiek County. The creek is sixteen miles in length with 26,223 acres of watershed area. Walnut Creek is listed on the 2008 impaired waters list as biologically impaired. Based on results of biological monitoring, no specific causes of the impairment have been identified. This watershed is of particular significance to the Poweshiek SWCD and the state of Iowa because water quality protection efforts can be implemented that will address the impairment. The Poweshiek SWCD received a watershed development grant in 2005, to complete a watershed assessment for the Walnut Creek Watershed. The results of the assessments showed an estimated 23,224 tons of sediment are delivered annually to Walnut Creek, and, about 34% of land in the watershed is delivering nearly 66% of the sediment. Therefore, the acres with more than 1 ton/ac/yr sediment delivery have been prioritized. In Jan. 2008, an implementation grant began. The 1st year’s EQIP matching funds were obligated by July 2008. Specific objectives are to: 1) Reduce sediment delivery by 3,205 tons, by installing conservation practices on the sediment delivery areas of more that 1 ton/ac/yr, and, 2) Develop an information and education program for landowners. The District has prioritized the Walnut Creek watershed for 50% EQIP funding to be combined with 25% WSPF funds. This application is for additional practice funds, utilized as 50% cost-share, to be used with 25% WSPF funds, for eligible soil loss projects (>1 ton/ac), when EQIP funds are not available.

Control dolor post quirúrgic pacients intervinguts hèrnia inguinal per CMA

El dolor post-operatori és un dels problemes més importants que segons la OMS afecta als pacients intervinguts quirúrgicament i el que més els preocupa. Any rere any hi ha un increment del nombre de pacients intervinguts per Cirurgia Major ambulatòria al nostre país de manera que ha de ser el mateix usuari i la família els que facilitin les cures als pacients al propi domicili. Aquest estudi planteja si introduir intervencions educatives al servei disminueix el dolor post-operatori dels usuaris Objectiu general: Dissenyar un programa d’informació que realitzarà infermeria dirigit als cuidadors i pacients del servei de CMA i que han de ser intervinguts de hèrnia engonal. Avaluar l’eficiència del mateix programa educatiu. Metodologia: l’àmbit d’estudi d’aquest treball serà les unitats de Cirurgia Major ambulatòria de qualsevol centre de Catalunya. Es realitzarà un estudi comparatiu quantitatiu entre dos grups independents integrants per 30 participants en cadascun d’ells (total de 60 participants). Grupo A: protocol habitual de la unitat Grup B: intervenció educativa dissenyada Els participants seran pacients majors d’edat, que compleixen els requisits per ser intervinguts per Cirurgia Major Ambulatòria de Hèrnia inguinal. El participant ha de fer-ho amb un familiar responsable de les seves cures. Es realitzaran 3 enquestes al pacient i 3 al familiar responsable de les cures, la primera a les 24 hores després de la intervenció, la segona a la setmana i l’última a les 2 setmanes. Limitacions de l’estudi: en cas de que el pacient que ha de formar part de l’estudi requereixi ingrés hospitalari per alguna complicació durant la cirurgia el pacient deixa de participar en l’estudi automàticament. En cas que el pacient o familiar no contestin al telèfon el dia i l’hora pactada prèviament també deixarà de formar part de la investigació. Per aquest motiu es tindran 10 pacients de reserva per si calgués reemplaçar el subjecte d’estudi.

1016-010 Iowa Great Lakes Watershed Final Report

Part of a phased approach, an intensive information and education program, construction of erosion control practices, and sediment control on construction sites is proposed. These proposed practices will manage sediment runoff and nutrient runoff on agricultural and urban areas. Sediment control “structures” such as waterways, wetlands, modified terraces, grade stabilization structures, sediment basins, and rain gardens is proposed and will be combined with nutrient and pesticide management and reduced tillage to reduce non-point source pollution. A reduction of 15% of the sediment and phosphorus delivered to a water body from priority areas will be looked at as a success in this short-term project focused primarily at education within the project area which is also, for the most part, the top 25% sediment load producing sub-watersheds. In addition, four urban areas have been identified as part of this project as needing immediate assistance. A combination of urban and agricultural conservation practices, shoreline revegetation, and education of landowners will be used to achieve these results on both the urban and the agricultural arena.

Predictive Value of Readiness, Importance, and Confidence in Ability to Change Drinking and Smoking

Background: Visual analog scales (VAS) are used to assess readiness to changeconstructs, which are often considered critical for change.Objective: We studied whether 3 constructs -readiness to change, importance of changing and confidence inability to change- predict risk status 6 months later in 20 year-old men with either orboth of two behaviors: risky drinking and smoking. Methods: 577 participants in abrief intervention randomized trial were assessed at baseline and 6 months later onalcohol and tobacco consumption and with three 1-10 VAS (readiness, importance,confidence) for each behavior. For each behavior, we used one regression model foreach constructs. Models controlled for receipt of a brief intervention and used thelowest level (1-4) in each construct as the reference group (vs medium (5-7) and high(8-10) levels).Results: Among the 475 risky drinkers, mean (SD) readiness, importance and confidence to change drinking were 4.0 (3.1), 2.8 (2.2) and 7.2 (3.0).Readiness was not associated with being alcohol-risk free 6 months later (OR 1.3[0.7; 2.2] and 1.4 [0.8; 2.6] for medium and high readiness). High importance andhigh confidence were associated with being risk free (OR 0.9 [0.5; 1.8] and 2.9 [1.2;7.5] for medium and high importance; 2.1 [1.0;4.8] and 2.8 [1.5;5.6] for medium andhigh confidence). Among the 320 smokers, mean readiness, importance andconfidence to change smoking were 4.6 (2.6), 5.3 (2.6) and 5.9 (2.6). Neitherreadiness nor importance were associated with being smoking free (OR 2.1 [0.9; 4.7]and 2.1 [0.8; 5.8] for medium and high readiness; 1.4 [0.6; 3.4] and 2.1 [0.8; 5.4] formedium and high importance). High confidence was associated with being smokingfree (OR 2.2 [0.8;6.6] and 3.4 [1.2;9.8] for medium and high confidence).Conclusions: For drinking and smoking, high confidence in ability to change wasassociated -with similar magnitude- with a favorable outcome. This points to thevalue of confidence as an important predictor of successful change.

07021-008 Sand Creek Watershed Final Report

Sand Creek is the most significant recreational fishery in Delaware County because of its location to Manchester and Lake Delhi. It is a feeder stream for game fish to the main stem of the Maquoketa River which is limited by the dams at Manchester and Lake Delhi. Sand Creek encompasses 16,045 acres and is dominated by row crop agriculture. It is being impacted by sediment, nutrients and E coli bacteria. Sand Creek will be a good example for habitat impaired watershed. The purpose of this project is to decrease the amount of sediment and nutrients reaching Sand Creek and to increase the habitat in Sand Creek to make it a better spawning and growing area for the fish and the food chain for the fish. The objectives of this project are to reduce sediment delivery by 40%, to improve in-stream habitat on 40% of identified critical areas and implement an information/education program. The project will install 3,800 acres of new no-till planting, 6 water and sediment control basins, 4,000 feet of terraces, 20,000 feet of improved or new waterways, 3,200 feet of streambank/ habitat enhancement, 4,500 feet of livestock exclusion fencing and 6 acres of wetlands.

1240-017 Little Bear Creek Watershed Final Report

Little Bear Creek is a 21.79 mile Class A1 and B (WW2) warm water stream that encompasses approximately 29,202 acres in northern Poweshiek County. The lower 8.4 mile segment is listed as biologically impaired on both the IDNR 2008 303(d) list and 2010 303(d) draft list. A RASCAL assessment and landowner survey was completed through a development grant in 2011, and these assessments indicate that erosion and sediment delivery from cropland, lack of adequate buffers along the stream channel, and streambank conditions contribute significant sediment delivery to the stream, likely resulting in the impairment. An estimated 36,544 tons of sediment are delivered to the stream annually. A total of 11,075 acres (38%) of the watershed are high priority areas or land with sediment delivery rates greater than one. Our goal over 15 years is to install Best Management Practices (BMPs) and increase public education in order to reduce sediment and phosphorus delivery by 25% and decrease priority areas by 15%. More specific objectives for this WIRB project are to 1) Reduce annual sediment delivery by roughly 16.3% or 1,058 tons and associated phosphorus delivery by 1,375 pounds and 2) Develop an information and education program aimed at producers and residents within the headwaters of Grant and Chester townships, which account for 18% of the watershed's priority areas. The SWCD proposes to utilize 50% EQIP funds and 25% WIRB funds toward rural BMPs, and 75% WIRB funds toward urban BMPs received through this application.

A course on collaboration between social workers and general practitioners during their vocational training

The educational programme reported was an experiment in the vocational training scheme of the department of General Practice, Erasmus University, Rotterdam, Holland, and is now part of the course. The programme focused on the training in team function (co-operation) given to trainee GPs and social workers. It became clear that both groups during their professional training develop markedly different attitudes and views about patient (client) care. These differences form a fundamental handicap in any discussion about teamwork. During the programme the students were made aware of this divergence of viewpoint and were taught how to handle these resulting handicaps and, if possible, to eliminate them.

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.

Training needs in adolescent medicine of practising doctors: a Swiss national survey of six disciplines.

OBJECTIVE: To assess and compare the training needs in adolescent medicine of doctors within 6 specialties as a basis for the development of pre/postgraduate and continuing medical education (CME) training curricula. DESIGN: Cross-sectional postal survey. SETTING: Switzerland. PARTICIPANTS: National, representative, random sample of 1857 practising doctors in 6 disciplines (general practitioners, paediatricians, gynaecologists, internists, psychiatrists, child psychiatrists) registered with the Swiss Medical Association. MAIN OUTCOME MEASURES: Perceived importance of and training interest in 35 topics related to adolescent medicine listed in a self-administered, anonymous questionnaire. RESULTS: A total of 1367 questionnaires were returned, representing a response rate of 73.9%. Clear interest in adolescent medicine was reported by 62.1% of respondents. Topics perceived to be the most important in everyday practice were functional symptoms (71.4%), acne (67.1%), obesity (64.6%), depression-anxiety (68.1%) and communication with adolescents (61.7%). Differences between disciplines were especially marked for gynaecologists, who expressed interest almost exclusively in medical topics specific to their field. In contrast, other disciplines commonly reported a keen interest in psychosocial problems. Accordingly, interest in further training was expressed mostly for functional symptoms (62.4%), eating disorders (56.3%), depression-anxiety (53.7%) and obesity (52.6%). Issues related to injury prevention, chronic disease and confidentiality were rated as low priorities. CONCLUSIONS: Regardless of discipline, Swiss primary care doctors expressed a strong interest in adolescent medicine. Continuing medical education courses should include both interdisciplinary courses and discipline-specific sessions. Further training should address epidemiological and legal/ethical issues (e.g. injury prevention, confidentiality, impact of chronic conditions).

When physician-expressed uncertainty leads to patient dissatisfaction: a gender study.

CONTEXT: Communication guidelines often advise physicians to disclose to their patients medical uncertainty regarding the diagnosis, origin of the problem, and treatment. However, the effect of the expression of such uncertainty on patient outcomes (e.g. satisfaction) has produced conflicting results in the literature that indicate either no effect or a negative effect. The differences in the results of past studies may be explained by the fact that potential gender effects on the link between physician-expressed uncertainty and patient outcomes have not been investigated systematically. OBJECTIVES: On the basis of previous research documenting indications that patients may judge female physicians by more severe criteria than they do male physicians, and that men are more prejudiced than women towards women, we predicted that physician-expressed uncertainty would have more of a negative impact on patient satisfaction when the physician in question was female rather than male, and especially when the patient was a man. METHODS: We conducted two studies with complementary designs. Study 1 was a randomised controlled trial conducted in a simulated setting (120 analogue patients Analogue patients are healthy participants asked to put themselves in the shoes of real medical patients by imagining being the patients of physicians shown on videos); Study 2 was a field study conducted in real medical interviews (36 physicians, 69 patients). In Study 1, participants were presented with vignettes that varied in terms of the physician's gender and physician-expressed uncertainty (high versus low). In Study 2, physicians were filmed during real medical consultations and the level of uncertainty they expressed was coded by an independent rater according to the videos. In both studies, patient satisfaction was assessed using a questionnaire. RESULTS: The results confirmed that expressed uncertainty was negatively related to patient satisfaction only when the physician was a woman (Studies 1 and 2) and when the patient was a man (Study 2). CONCLUSIONS: We believe that patients have the right to be fully informed of any medical uncertainties. If our results are confirmed in further research, the question of import will refer not to whether female physicians should communicate uncertainty, but to how they should communicate it. For instance, if it proves true that uncertainty negatively impacts on (male) patients' satisfaction, female physicians might want to counterbalance this impact by emphasizing other communication skills.
