Reaching C-Reactive Protein and Low-Density Lipoprotein Cholesterol Goals in Dyslipidemic Patients (from the Lipid Treatment Assessment Project [L-TAP] 2)

The purpose of the present substudy of the Lipid Treatment Assessment Project 2 was to assess dual C-reactive protein (CRP) and low-density lipoprotein (LDL) cholesterol goal attainment across a spectrum of low-, moderate-, and high-risk patients with dyslipidemia in 8 countries in North America, Latin America, Europe, and Asia. Of the 9,518 patients studied overall, 45% were women, 64% had hypertension, 31% had diabetes, 14% were current smokers, 60% were high risk, and 79% were taking a statin. The median CRP level was 1.5 mg/L (interquartile range 0.2 to 2.8). On multivariate analysis, higher CRP levels were associated with older age, female gender, hypertension, current smoking, greater body mass index, larger waist circumference, LDL cholesterol level, and triglyceride/high-density lipoprotein cholesterol ratio. In contrast, being from Asia or taking a statin was associated with lower levels. Across all risk groups, 59% of patients attained the CRP target of <2 mg/L, and 33% had <1 mg/L. Overall, 44% of patients attained both their National Cholesterol Education Program Adult Treatment Panel III LDL cholesterol target and a CRP level of <2 mg/L, but only 26% attained their LDL cholesterol target and a CRP level of <1 mg/L. In the very high-risk group with coronary heart disease and >= 2 risk factors, only 19% attained both their LDL cholesterol goal and a CRP level of <2 mg/L and 12% their LDL cholesterol goal and a CRP level of <1 mg/L. In conclusion, with current treatment, most dyslipidemic patients do not reach the dual CRP and LDL cholesterol goals. Smoking cessation, weight reduction, and the greater use of more potent statins at higher doses might be able to improve these outcomes. (C) 2011 Elsevier Inc. All rights reserved.

Lipid goals among patients with diabetes or metabolic syndrome: Lipid Treatment Assessment Project (L-TAP) 2

Objective: This analysis of the Lipid Treatment Assessment Project 2 population compared lipid goal attainment by diabetes and metabolic syndrome status. Research design and methods: Dyslipidaemic patients aged >= 20 years on stable lipid lowering therapy had their lipid levels determined once during enrolment at investigation sites in nine countries between September 2006 and April 2007. Achievement of low-density lipoprotein (LDL) cholesterol success, triglycerides < 150 mg/dl (1.7 mmol/l), and high-density lipoprotein (HDL) cholesterol success (> 40 mg/dl [1.0 mmol/l] in men or > 50 mg/dl [1.3 mmol/l] in women) was compared using logistic regression. Results: A total of 9955 patients were evaluated. Patients with diabetes, compared with those without diabetes, had lower achievement of LDL cholesterol goals (according to National Cholesterol Education Program Adult Treatment Panel [NCEP ATP] III guidelines; 67% vs. 75%), triglycerides < 150 mg/dl (55% vs. 64%), and HDL cholesterol success (61% vs. 74%; p < 0.0001 for all comparisons). The significantly lower lipid goal attainment in patients with diabetes was consistent across participating world regions. Patients with metabolic syndrome, compared with those without metabolic syndrome, had lower achievement of NCEP ATP III LDL cholesterol goals (69% vs. 76%), triglycerides < 150 mg/dl (36% vs. 83%), and HDL cholesterol success (49% vs. 89%; p < 0.0001 for all comparisons). As the number of metabolic syndrome components increased, lipid success rates progressively decreased (p < 0.0001 for LDL cholesterol success, triglycerides < 150 mg/dl, and HDL cholesterol success). Conclusions: This analysis indicates that despite their increased cardiovascular risk, patients with diabetes or metabolic syndrome remain undertreated.

Hábitos alimentares aterogênicos de grupos populacionais em área metropolitana da região sudeste do Brasil

Em amostra representativa da população de duas áreas de estudo (568 indivíduos), Município de Cotia, SP, Brasil, foi realizado inquérito alimentar, baseado na história alimentar do indivíduo. Os objetivos foram: identificar o potencial aterogênico de dietas de diferentes agrupamentos humanos, estratificados em classes sociais e analisar diferenciais de consumo de alguns nutrientes, que conferem aterogenicidade à dieta entre esses agrupamentos. Foram analisados diferenciais de consumo, entre homens e mulheres, segundo classes sociais e tomando-se como referência o percentil 50 (P50) da amostra, dos seguintes constituintes da dieta: energia, proteínas totais, proteínas de origem animal, percentagem de calorias protéicas (P%), ácidos graxos, gorduras, carboidratos. Seguindo esse critério, foram analisados perfis de dieta em relação às recomendações do National Cholesterol Education Program (NEP) no que diz respeito às calorias fornecidas pelas gorduras (G >30%), ac. graxos saturados (AGS> 10%), carboidratos (HC>60%) e colesterol (>300mg/dia). Os resultados mostraram que os diferenciais de consumo foram mais pronunciados entre os homens do que entre as mulheres. As classes sociais, entre os homens, que apresentaram maiores percentuais acima do P50 da amostra, no que diz respeito à energia , proteínas totais, gorduras e carboidratos, foram as representadas pelos trabalhadores não qualificados, que se dedicam a trabalhos braçais com alto consumo energético e a dos pequenos proprietários e comerciantes. A classe de maior poder aquisitivo e nível educacional apresentou consumo moderado desses constituintes. O consumo de proteínas de origem animal, acima do P50, entre homens e mulheres, guardou relação direta com o nível socioeconômico da classe . A participação calórica das gorduras (G%) e proteínas (P%) foi diretamente proporcional ao poder aquisitivo da classe, ao passo que a dos carboidratos (HC%) guardou relação inversa. Por outro lado, o consumo de colesterol acima de 300mg/dia situou-se nas faixas de 37 a 50% e de 20 a 32% para os homens e mulheres, respectivamente. A percentagem de dietas com calorias provenientes das gorduras (G%) acima de 30% variou de 25 a 40%, para os homens e de 45 a 50% para as mulheres. A participação dos ácidos graxos saturados (AGS%) em proporções maiores ou iguais a 10 foi relativamente baixa para ambos os sexos: de 5 a 17% para os homens e menos de 10% para as mulheres. Os percentuais de casos em que a relação ácidos graxos saturados e insaturados (AGS/AGI) guardou valores menores ou iguais a 1, também foi baixa para a população em geral; situou-se entre 7 e 22% para os homens e em proporções abaixo de 10%, para as mulheres. Concluiu-se que a dieta se apresenta como provável fator de risco de doenças cardiovasculares, dislipidemias, obesidade e hipertensão, para grande parte da população.

Avaliação dos serviços de saúde mental em Moçambique

RESUMO: O instrumento de avaliação de sistemas de saúde mental da organização mundial de saúde (WHO-AIMS)foi usado para a recolha de informações sobre o Programa Nacional de Saúde Mental de Moçambique. O presente estudo tem como objectivo melhorar o Programa Nacional de Saúde Mental e fornecer um ponto de partida para a monitorização das mudanças. Os resultados do estudo permitirão a Moçambique fortalecer a sua capacidade para desenvolver planos de saúde mental baseados em informações com pontos de partida e metas bem definidos. O relatório será também útil para a monitorização do progresso da implementação de reformas nas políticas de saúde mental, na disponibilização de serviços de base comunitária, e no envolvimento dos utentes, seus familiares e outros actores na promoção, prevenção,cuidados e reabilitação em saúde mental. Tendo em conta os antecedentes históricos da saúde mental em Moçambique, a realidade actual clama por reformas profundas voltadas para uma intervenção mais humanizada e com enfoque nos cuidados primários. É nesse contexto que o estudo realizado apresenta resultados relacionados com as políticas, legislação, estratégias e planos de acção e financiamento para a saúde mental; serviços de saúde mental;cuidados primários; recursos humanos e ligação com outros sectores chave. A saúde mental foi avaliada desde o sistema de gestão até ao nível comunitário. Relativamente aos órgãos de gestão, a principal constatação é que existem instrumentos legais para sustentar as iniciativas desta área e influenciar os meios políticos em prol da saúde mental. Todavia, o caminho a percorrer ainda é longo uma vez que não está ainda aprovada nenhuma lei de saúde mental e os financiamentos para a área não permitem a implementação das reformas necessárias. Os serviços ao nível clínico debatem-se com a problemática dos recursos humanos (constituídos principalmente por técnicos de psiquiatria) e disponibilidade de psicofármacos. O modelo biopsicossocial ainda não é implementado integralmente uma vez que são poucos os serviços que oferecem apoio psicossocial (que inclui a reabilitação e reintegração) para além da intervenção farmacológica. Esta pode ser considerada uma das principais causas de recaídas identificadas em todas as províncias. Há uma necessidade urgente de se realizarem pesquisas e levantamentos epidemiológicos que possam servir de suporte para a advocacia em saúde mental com vista a melhoria dos cuidados a prestar aos pacientes e comunidade. Os instrumentos de recolha de informação de rotina não são adequados limitando a fidelidade dos dados recolhidos e a possibilidade de uma gestão dos serviços de saúde mental que responda as reais necessidades da população. Em suma, os resultados aqui apresentados mostram que Moçambique tem uma base que pode ser considerada uma mais valia para a reforma do sistema de saúde mental. Existem, ainda que escassos, recursos como humanos, infra-estruturas e legislação para a prestação dos serviços clínicos. É preciso investir na saúde mental para que os recursos existentes sejam melhorados e expandidos, apostando na criação de equipas multidisciplinares e qualificação das equipas de gestão e equipas clínicas. --------ABSTRACT: The World Health Organization Assessment Instrument for Mental Health Services (WHO-AIMS) was used to collect information about the National Mental Health Program of Mozambique. The present study aims to improve the National Mental Health Program and provide a starting point for monitoring change. The study results will allow Mozambique to strengthen its capacity to develop mental health plans based on information with starting points and well-defined goals. The report will also be useful for monitoring the progress of implementation of reforms in mental health policies, the provision of community-based services, and involvement of users, their families and other stakeholders in the promotion, prevention, care and rehabilitation in mental health. Given the historical background of mental health in Mozambique, the current situation calls for reforms aimed at a more humane intervention focused on primary care. In this context, the study presents results related to policies, legislation, strategies and action plans and funding for mental health; mental health services; primary care; human resources and liaison with other key sectors. Mental health was assessed from the management system to the community level. With regard to the management, the main observation is that there are legal instruments to support the initiatives in this area and to influence the political means on behalf of mental health. However, the pathway is still long as it is not yet approved any Mental Health Law and the funding for the area do not allow the implementation of necessary reforms. Services at the clinical level are struggling with the issue of human resources (consisting primarily of psychiatrist technicians) and availability of psychotropic drugs. The biopsychosocial model is not yet fully implemented since there are few services providing psychosocial support (including rehabilitation and reintegration) in addition to pharmacological intervention. This can be considered a major cause of relapse identified in all provinces. There is an urgent need to conduct research and epidemiological surveys which could provide support for advocacy in mental health in order to improve the mental health car for the patients and community. The routine data collection instruments are not appropriate limiting the fidelity of the data collected and the possibility of a management of mental health services that meets the real needs of the population. In summary, the results presented here show that Mozambique has a groundwork that can be considered an asset for the reform of mental health system. There are, though scarce, human resources, infrastructure and legislation for the provision of clinical services. It’s necessary to invest in mental health so that existing resources are improved and expanded, and to invest on the creation of multidisciplinary teams and qualification of management teams and clinical teams.

Primary multidrug-resistant tuberculosis and its control implications in the State of Amazonas, Brazil: report of 3 cases

The occurrence of tuberculosis with first-line multidrug resistance leads to the use of alternative medications, often at higher costs, longer treatment periods, and greater clinical complexity. Here, we report 3 patients with multidrug-resistant tuberculosis. One patient with human immunodeficiency virus died before the sensitivity test was performed. The early diagnosis of multidrug-resistant tuberculosis and appropriate treatment should be priorities of the National Tuberculosis Control Program in order to break the chain of transmission. In addition, the possibility of substituting the proportion method with more modern and faster techniques should be urgently evaluated.

Anopheles darlingi and Anopheles marajoara (Diptera: Culicidae) susceptibility to pyrethroids in an endemic area of the Brazilian Amazon

Abstract: INTRODUCTION: This study aimed to evaluate the susceptibility of Anopheles darlingi Root (1926) and Anopheles marajoara Galvão & Damasceno (1942) to pyrethroids used by the National Malaria Control Program in Brazil. METHODS: Mosquitoes from Amapá, Brazilian Amazon, were assessed for resistance to cypermethrin, deltamethrin, and alpha-cypermethrin. Insecticide-impregnated bottles were used as suggested by the CDC/Atlanta. RESULTS: Diagnostic dose for Anopheles darlingi was 12.5µg/bottle during 30 min of exposure. Concentrations for Anopheles marajoara were 20µg/bottle of cypermethrin and deltamethrin and 12.5µg/bottle of alpha-cypermethrin. CONCLUSIONS : No resistance was recorded for Anopheles darlingi , but Anopheles marajoara requires attention.

Self-monitoring of freeze–thaw damage using triphasic electric conductive concrete

The effect of freeze–thaw cycles on concrete is of great importance for durability evaluation of concrete structures in cold regions. In this paper, damage accumulation was studied by following the fractional change of impedance (FCI) with number of freeze–thaw cycles (N). The nano-carbon black (NCB), carbon fiber (CF) and steel fiber (SF) were added to plain concrete to produce the triphasic electrical conductive (TEC) and ductile concrete. The effects of NCB, CF and SF on the compressive strength, flexural properties, electrical impedance were investigated. The concrete beams with different dosages of conductive materials were studied for FCI, N and mass loss (ML), the relationship between FCI and N of conductive concrete can be well defined by a first order exponential decay curve. It is noted that this nondestructive and sensitive real-time testing method is meaningful for evaluating of freeze–thaw damage in concrete.

Rockburst laboratory tests database - Application of data mining techniques

Rockburst is characterized by a violent explosion of a block causing a sudden rupture in the rock and is quite common in deep tunnels. It is critical to understand the phenomenon of rockburst, focusing on the patterns of occurrence so these events can be avoided and/or managed saving costs and possibly lives. The failure mechanism of rockburst needs to be better understood. Laboratory experiments are undergoing at the Laboratory for Geomechanics and Deep Underground Engineering (SKLGDUE) of Beijing and the system is described. A large number of rockburst tests were performed and their information collected, stored in a database and analyzed. Data Mining (DM) techniques were applied to the database in order to develop predictive models for the rockburst maximum stress (σRB) and rockburst risk index (IRB) that need the results of such tests to be determined. With the developed models it is possible to predict these parameters with high accuracy levels using data from the rock mass and specific project.

Concrete with triphasic conductive materials for self-monitoring of cracking development subjected to flexure

In this study, the macro steel fiber (SF), carbon fiber (CF) and nano carbon black (NCB) as triphasic conductive materials were added into concrete, in order to improve the conductivity and ductility of concrete. The influence of NCB, SF and CF on the post crack behavior and conductivity of concrete was explored. The effect of the triphasic conductive materials on the self-diagnosing ability to the load–deflection property and crack widening of conductive concrete member subjected to bending were investigated. The relationship between the fractional change in surface impedance (FCR) and the crack opening displacement (COD) of concrete beams with conductive materials has been established. The results illustrated that there is a linear relationship between COD and FCR.

Influence of different fibers on the change of pore pressure of self-consolidating concrete exposed to fire

The focus of this paper is given to investigate the effect of different fibers on the pore pressure of fiber reinforced self-consolidating concrete under fire. The investigation on the pore pressure-time and temperature relationships at different depths of fiber reinforced self-consolidating concrete beams was carried out. The results indicated that micro PP fiber is more effective in mitigating the pore pressure than macro PP fiber and steel fiber. The composed use of steel fiber, micro PP fiber and macro PP fiber showed clear positive hybrid effect on the pore pressure reduction near the beam bottom subjected to fire. Compared to the effect of macro PP fiber with high dosages, the effect of micro PP fiber with low fiber contents on the pore pressure reduction is much stronger. The significant factor for reduction of pore pressure depends mainly on the number of PP fibers and not only on the fiber content. An empirical formula was proposed to predict the relative maximum pore pressure of fiber reinforced self-consolidating concrete exposed to fire by considering the moisture content, compressive strength and various fibers. The suggested model corresponds well with the experimental results of other research and tends to prove that the micro PP fiber can be the vital component for reduction in pore pressure, temperature as well spalling of concrete.

Lipid profile and cardiovascular risk in two Amazonian populations

OBJECTIVE: To compare the lipid profiles and coronary heart disease risks of 2 Brazilian Amazonian populations as follows: a riverside population (village of Vigia) and an urban population (city of Belém in the state of Pará). METHODS: Fifty individuals controlled for age and sex were assessed in each region, and the major risk factors for coronary heart disease were analyzed. RESULTS: According to the National Cholesterol Education Program (NCEP III) and using the Framingham score, both populations had the same absolute risk of events (Vigia = 5.4 ± 1 vs Belém = 5.7 ± 1), although the population of Vigia had a lower consumption of saturated fat (P<0.0001), a greater consumption of mono- and polyunsaturated fat (P<0.03), in addition to lower values for body mass index (25.4± 0.6 vs 27.6 ± 0.7 kg/m², P<0.02), of biceps skin fold (18.6 ± 1.1 vs 27.5 ± 1.3 mm, P<0.0001), of triceps skin fold (28.7 ± 1.2 vs 37.3 ± 1.7 mm, P<0.002), and of total cholesterol (205 ± 5 vs 223 ± 6 mg/dL, P< 0.03) and triglycerides (119 ± 9 vs 177 ± 18 mg/dL, P<0.005). Both populations did not differ in regard to HDL-C (46 ± 1 vs 46 ± 1 mg/dL), LDL-C (135 ± 4 vs 144 ± 5 mg/dL) and blood pressure (SBP 124 ± 3 vs 128 ± 3 mmHg; DBP 80 ± 2 vs 82 ± 2 mmHg). CONCLUSION: The riverside and urban populations of Amazonia had similar cardiovascular risks. However, the marked difference in the variables studied suggests that different strategies of prevention should be applied.

Prevalência de síndrome metabólica em idosos de uma comunidade: comparação entre três métodos diagnósticos

FUNDAMENTO: A prevalência de síndrome metabólica (SM), encontrada em diferentes estudos, tem apresentado ampla variação dependendo da população e do critério diagnóstico utilizado, havendo uma tendência de maior prevalência da SM com o critério diagnóstico da International Diabetes Federation (IDF). OBJETIVO: Comparar a prevalência da SM com diferentes critérios em idosos de uma comunidade. MÉTODOS: Este é um estudo transversal, de base populacional, realizado na cidade de Novo Hamburgo - RS, Brasil -, do qual participaram 378 idosos com 60 anos ou mais (252 mulheres e 126 homens). A prevalência da SM foi estimada aplicando os critérios diagnósticos do National Cholesterol Education Program - Adult Treatment Panel III (NCEP ATPIII) (2001), do NCEP ATPIII revisado (2005) e da IDF. RESULTADOS: A prevalência de SM aumentou progressivamente com a utilização dos critérios do NCEP ATP III, NCEP ATP III revisado e da IDF, apresentando valores de 50,3%, 53,4% e 56,9%, respectivamente. O aumento progressivo da prevalência de SM com a utilização dos três critérios ocorreu em ambos os sexos, com maior prevalência entre as mulheres, com percentuais de 57,1%, 59,9% e 63,5% com os critérios do NCEP ATP III, NCEP ATP III revisado e da IDF, respectivamente. CONCLUSÃO: Utilizando o critério da IDF, encontrou-se uma maior prevalência de SM em relação à prevalência encontrada com o critério do NCEP ATP III e NCEP ATP III revisado. A prevalência da SM foi maior entre as mulheres, independente do critério utilizado.
