Aumento do trabalho miocárdico desperdiçado como indicador de lesão coronariana significativa / Increased wasted myocardial work as an indicator of significant coronary lesion

Introdução: A avaliação dos índices de trabalho miocárdico global em condições basais pode ser útil para a estratificação clínica de pacientes com suspeita de obstrução coronariana. Objetivo: Correlacionar o valor do índice de trabalho miocárdico global e a presença de lesões obstrutivas coronarianas significativas. Método: Estudo transversal, com pacientes encaminhados para cinecoronarioangiografia eletiva. Foi realizado ecocardiograma com obtenção das medidas para cálculo do valor do trabalho miocárdico, sendo avaliada a presença de lesões obstrutivas coronarianas significativas à cinecoronarioangiografia. Resultados: A amostra foi composta de 30 pacientes, com a idade média de 64,2±12,8 anos, sendo a maioria do sexo masculino (63,3%), dos quais 68,4% apresentaram lesões obstrutivas coronarianas significativas. O índice de trabalho miocárdico global foi de 1.876mmHg%±253,8 no grupo com lesões obstrutivas coronarianas significativas e de 2.054,2mmHg%±417,3 naqueles sem lesões significativas (p=0,089). O trabalho miocárdio construtivo global nos pacientes sem lesões obstrutivas coronarianas significativas foi maior (2.329,3mmHg%±462,9) do que naqueles com lesões obstrutivas coronarianas significativas (2.109,5mmHg%±332,3; p=0,064). O trabalho miocárdio desperdiçado global foi maior nos pacientes com lesões obstrutivas coronarianas significativas (103,7mmHg%±47,1 versus 68,3mmHg%±33,8; p=0,038). O ponto de corte de 115mmHg% foi aquele com a melhor área sob a curva (0,625), com sensibilidade de 83,3%. Conclusão: O aumento do trabalho miocárdio desperdiçado global se correlacionou com a presença de lesões obstrutivas coronarianas significativas em nossa amostra.(AU)

Introduction: The assessment of global myocardial work indices under baseline conditions may be useful for the clinical stratification of patients with suspected coronary obstruction. Objective: To correlate the value of global myocardial work indices and the presence of significant obstructive coronary lesions. Method: Cross-sectional study, with patients referred for elective coronary angiography. An echocardiogram was performed to obtain measurements to calculate the value of myocardial work and evaluated the presence or presence of significant obstructive coronary lesions at coronary angiography. Results: The sample consisted of 30 patients, with a mean age of 64.2±12.8 years, the majority being male (63.3%), of which 68.4% had significant obstructive coronary lesions. The global myocardial work indices was 1,876mmHg%±253.8 in the group with significant obstructive coronary lesions and 2,054.2mmHg%±417.3 in those without significant lesions (p=0.089). Global constructive myocardial work in patients without significant obstructive coronary lesions was higher (2,329.3mmHg%±462.9) than in those with significant obstructive coronary lesions (2,109.5mmHg%±332.3; p=0.064). Global wasted myocardial work was higher in patients with significant obstructive coronary lesions (103.7mmHg%±47.1 versus 68.3mmHg%±33.8; p=0.038). The cutoff point of 115 mmHg% was the one with the best area under the curve (0.625), with a sensitivity of 83.3%. Conclusion: The increase in global wasted myocardial work correlated with the presence of significant obstructive coronary lesions in our sample. (AU)

Pterygium Surgery with Conjunctival Autograft Fixation Using Bipolar Electrocauterization.

PURPOSE: To report a case series of pterygium surgery with conjunctival autograft fixation using bipolar electrocautery. DESIGN: A noncomparative, retrospective, interventional case series of pterygium surgery with follow-up longer than 12 months to assess recurrence and other complication rates. PARTICIPANTS: Fifty-six eyes of 37 patients were treated between April 2011 and January 2018, either for primary (n = 53 cases) or recurrent (n = 3 cases) pterygia. INTERVENTION: After pterygium excision, free conjunctival grafts from the inferior bulbar conjunctiva of the same eye were harvested and fixated with the use of bipolar electrocautery. MAIN OUTCOME MEASURE: Recurrence of the pterygium and complications. RESULTS: The mean follow-up was 41 months (range 12 to 81 months). There were no intraoperative complications. Recurrence of the lesion was seen in three eyes (5.36%). There were no other postoperative complications such as graft detachment, or formation of dellen or granulomas. CONCLUSION: Conjunctival autograft fixation using bipolar electrocautery seems to be a fast, costly and safe procedure that can be applied in most cases of pterygium surgery.

Metabolic syndrome, insulin resistance and other cardiovascular risk factors in university students.

A cross-sectional population-based study using questionnaire and anthropometric data was conducted on 968 university students of São Luís, Brazil, from which 590 showed up for blood collection. In the statistical analysis the Student t-test, Mann-Whitney and chi-square tests were used. The prevalence of metabolic syndrome by the Joint Interim Statement (JIS) criteria was 20.5%, almost three times more prevalent in men (32.2%) than in women (13.5%) (P < 0.001). The prevalence of insulin resistance was 7.3% and the prevalence of low HDL-cholesterol was high (61.2%), both with no statistically significant differences by sex. Men showed a higher percentage of smoking, overweight, high blood pressure, high blood glucose and increased fasting hypertriglyceridemia. Women were more sedentary. University students of private institutions had higher prevalences of sedentary lifestyle, obesity, abdominal obesity, elevated triglycerides and metabolic syndrome than students from public institutions. High prevalences of metabolic syndrome, insulin resistance and other cardiovascular risk factors were found in this young population. This suggests that the burden of these diseases in the future will be increased.

Resumo Estudo transversal de base populacional, usando questionários e medidas antropométricas, feito em 968 universitários de São Luís, dos quais 590 realizaram também coleta de sangue. Na análise estatística foram utilizados os testes t de Student, Mann-Whitney e qui-quadrado. A prevalência de síndrome metabólica pelo critério Joint Interim Statement (JIS) foi de 20,5%, sendo quase três vezes mais prevalente nos homens (32,2%) do que nas mulheres (13,5%) (P < 0,001). A prevalência de resistência insulínica foi de 7,3% e a de HDL-colesterol diminuído foi elevada (61,2%), ambas sem diferença estatisticamente significante por sexo. Os homens apresentaram maior percentual de tabagismo, sobrepeso, hipertensão arterial, glicemia em jejum aumentada e hipertrigliceridemia. As mulheres eram mais sedentárias. Os universitários de instituições privadas tiveram maiores prevalências de sedentarismo, obesidade, obesidade abdominal, triglicerídeos aumentados e síndrome metabólica do que os alunos de instituições públicas. Prevalências elevadas de síndrome metabólica, resistência insulínica e outros fatores de risco cardiovascular foram encontradas nesta população jovem. Isto sugere que a carga destas doenças será elevada no futuro.

The association between cardiovascular risk factors and anthropometric obesity indicators in university students in São Luís in the State of Maranhão, Brazil.

The article aims to evaluate the relation between cardiovascular risk factors (CVRF) and anthropometric indicators in a sample of university students from São Luís-MA, Brazil. It is a cross-sectional study conducted with 968 university students, with median age of 22. Glycemia, triglycerides, HDL-c, smoking, alcohol consumption, physical inactivity, metabolic syndrome (Joint Interim Statement criteria) and insulin resistance (IR), were associated and correlated with anthropometric indicators such as BMI, WC, WHR and WHtR. Associations were found between TGL, SH, SM and higher values of all anthropometric variables. The RI was associated with higher BMI values and WHtR in men and women. The low HDL-c was associated with higher values of all anthropometric variables in women. Consumption of alcohol was associated with higher values of BMI and WC in women and WHR in men and WHtR. Smoking was associated with higher values of WHtR in both sexes. Physical inactivity was associated with higher values of WHR in men only. The highest correlations were established for women between TGL and BMI CC, WHR and WHtR. The indicators most associated with CVRF were BMI, WC and WHtR in females and WHR and WHtR in men.

[Prevalence of subclinical atherosclerosis and cardiovascular risk reclassification by measure of carotid intima-media thickness in ambulatory hypertensive patients]. / Prevalência de aterosclerose subclínica e reclassificação de risco cardiovascular pela medida da espessura íntimo-medial carotídea em pacientes hipertensos ambulatoriais.

INTRODUCTION AND OBJECTIVES: Although carotid intima-media thickness (CIMT) is considered a surrogate marker of subclinical atherosclerosis, with known value in risk stratification, its routine use in hypertensive patients is not recommended. The aim of this study was to determine the prevalence of subclinical atherosclerosis through measurement of CIMT and its impact on reclassification of risk in hypertensive patients. METHODS: This was a cross-sectional study of 94 middle-aged (56.99±11.89 years) hypertensive outpatients without overt cardiovascular disease, 68.1% female. All participants underwent clinical examination, biochemical tests, echocardiogram and measurement of CIMT by high-resolution ultrasound. RESULTS: Although the majority of patients were stratified as low (63.5%) or intermediate risk (23%) according to their Framingham score, a high prevalence (75.3%) of increased CIMT was observed in the overall sample, including in the low (61%) and intermediate risk groups (93.8%). CIMT measurement resulted in risk reclassification of 70.31% of the patients, 61% of those at low risk being reclassified as intermediate risk and 93.8% of those at intermediate risk being reclassified as high risk. CONCLUSION: In these hypertensive outpatients, predominantly middle-aged and female, CIMT measurement revealed a high prevalence of subclinical atherosclerosis and resulted in risk reclassification in the majority of cases.

Correlação entre o índice de massa ventricular esquerda e a função endotelial em pacientes hipertensos / Correlation between left ventricular mass index and endothelial function in hypertensive patients

Fundamentos: Tanto a hipertrofia ventricular esquerda (HVE) como a disfunção endotelial representam importantes fatores de risco cardiovascular. No entanto, a correlação entre HVE e disfunção endotelial tem sido pouco explorada e ainda é motivo de controvérsias. Objetivo: Investigar a correlação entre o índice de massa do ventrículo esquerdo (IMVE) e a dilatação mediada por fluxo de artéria braquial (DMF), adotada como estimativa da função endotelial, em indivíduos hipertensos. Materiais e Métodos: Trata-se de estudo transversal envolvendo 94 hipertensos sem doença cardiovascular manifesta, com média de idade de 56,99 ± 11,89 anos, sendo 68,1% do sexo feminino. Todos os participantes foram submetidos a exame clínico, pesquisa de fatores de risco cardiovascular, dosagens bioquímicas, ecodopplercardiografia para determinação do IMVE e pesquisa da DMF por ultra-sonografia de alta resolução. Utilizouse a regressão linear múltipla para pesquisa da associação entre IMVE e DMF. Resultados: A média do IMVE foi de 104,4 ± 26,2 g/m2 e a da DMF, de 5,2 ± 5,7%. Na análise de regressão linear simples, observou-se uma correlação inversa significativa entre o IMVE e a DMF (ß = -0,389, p = 0,007). Após análise de regressão multivariada, a associação persistiu independentemente da pressão arterial, tanto sistólica quanto diastólica, proteína C reativa ultrassensível (PCR-US) e de outros fatores de risco cardiovascular. Conclusão: Observou-se correlação inversa significativa entre IMVE e DMF em hipertensos sem doença cardiovascular manifesta, independentemente da pressão arterial e do status inflamatório.

Background: Both left ventricular hypertrophy (LVH) and endothelial dysfunction represent important cardiovascular risk factors. However, the correlation between LVH and endothelial dysfunction has been little explored and is still a matter of controversies. Objective: To investigate the correlation between left ventricular mass index (LVMI) and flow-mediated dilation (FMD) of brachial artery , used as an estimative measure of endothelial dysfunction, in hypertensive patients. Materials and Methods: This is a cross-sectional study involving 94 middle-aged (56,99 ± 11,89 years) hypertensive outpatients without overt cardiovascular disease, being 68,1% female. All the participants underwent clinical examination, biochemical analyses, search for cardiovascular risk factors, transthoracic echocardiography for the determination of LVMI and assessment of FMD using a high-resolution Doppler B-mode ultrasound equipment. A multiple linear regression model was used to analyse the association between LVMI and DMF. Results: Mean LVMI was 104,4 ± 26,2 g/m2 and mean DMF, 5,2 ± 5,7%. Using simple linear regression, it was observed a significant inverse correlation between LVMI and FMD (ß = -0,389, p =0,007). This association remained significant even after adjustment for systolic and diastolic blood pressure, high sensitivity C-reactive protein (hs-CRP) and many other cardiovascular risk factors. Conclusions: In these hypertensive patients without overt cardiovascular disease, it was observed a significant inverse correlation between LVMI and FMD, which was independent of blood pressure and inflammatory status.

Síndrome metabólica e menopausa: estudo transversal em ambulatório de ginecologia / Metabolic syndrome and menopause: cross-sectional study in gynecology clinic / Síndrome metabólico y menopausia: estudio transversal en ambulatorio de ginecología

FUNDAMENTO: No Brasil, são escassos os estudos sobre síndrome metabólica na população geral, mais raros são os que a correlacionam ao climatério. OBJETIVO: Determinar a prevalência da síndrome metabólica e seus componentes em mulheres climatéricas. MÉTODOS: Estudo transversal com 323 mulheres climatéricas, divididas em dois grupos: pré e pós-menopausadas. Foram avaliadas para presença de síndrome metabólica, segundo os critérios do National Cholesterol Education Program's (NCEP) e da International Diabetes Federation (IDF). Foi verificada a associação entre as variáveis estudadas e a síndrome metabólica por meio de análise uni e multivariada. Um p-valor < 0,05 foi considerado significante estatisticamente. RESULTADOS: A prevalência de síndrome metabólica no climatério foi de 34,7 por cento (NCEP) e de 49,8 por cento (IDF). Os componentes mais frequentes da síndrome metabólica foram o HDL-colesterol baixo, hipertensão arterial, obesidade abdominal, hipertrigliceridemia e diabete em ambos os critérios. A análise multivariada mostrou que a idade foi o fator de risco mais importante para o surgimento da síndrome metabólica (p < 0,001), que esteve presente em 44,4 por cento (NCEP) e 61,5 por cento (IDF) das mulheres menopausadas em comparação a 24 por cento (NCEP) e 37 por cento (IDF) daquelas na pré-menopausa. CONCLUSÃO: A prevalência de síndrome metabólica foi maior nas mulheres menopausadas que naquelas na pré-menopausa. O principal fator de risco para o aumento dessa prevalência foi a idade. A menopausa, quando analisada isoladamente, não se constituiu um fator de risco para a síndrome metabólica.

BACKGROUND: In Brazil, there are few studies of the metabolic syndrome in the general population, and even fewer studies that establish a correlation between metabolic syndrome and climacteric. OBJECTIVE: To determine the prevalence of metabolic syndrome and its components among climacteric women. METHODS: Cross-sectional study with 323 climacteric women, divided into two groups: pre and post-menopausal. They were examined for the presence of metabolic syndrome, according to the criteria of National Cholesterol Education Program's (NCEP) and International Diabetes Federation (IDF). It was possible to notice the association between the variables under study and the metabolic syndrome by conducting a univariate analysis and a multivariate analysis. A p-value < 0.05 was considered statistically significant. RESULTS: The prevalence of metabolic syndrome during the climacteric was 34.7 percent (NCEP) and 49.8 percent (IDF). The most frequent components of the metabolic syndrome were low HDL-cholesterol, hypertension, abdominal obesity, hypertriglyceridemia and diabetes in both criteria. The multivariate analysis showed that age was the most important risk factor for the development of metabolic syndrome (p < 0.001), which was present in 44.4 percent (NCEP) and 61.5 percent (IDF) of postmenopausal women compared to 24 percent (NCEP) and 37 percent (IDF) of premenopausal women. CONCLUSION: The prevalence of metabolic syndrome was higher in postmenopausal women than in premenopausal women. The main risk factor for the increase in this prevalence was age. Menopause, when it is analyzed alone, did not constitute a risk factor for metabolic syndrome.

RESULTADOS: La prevalencia de síndrome metabólico en el climaterio fue de un 34,7 por ciento (NCEP) y de un 49,8 por ciento (IDF). Los componentes más frecuentes del síndrome metabólico fueron el HDL-colesterol bajo, hipertensión arterial, obesidad abdominal, hipertrigliceridemia y diabetes en ambos criterios. El análisis multivariado evidenció que la edad fue el factor de riesgo más importante para el surgimiento del síndrome metabólico (p<0.001), que estuvo presente en un 44,4 por ciento (NCEP) y un 61,5 por ciento (IDF) de las mujeres menopáusicas en comparación a 24 por ciento (NCEP) y el 37 por ciento (IDF) de aquellas en la premenopausia. CONCLUSIÓN: La prevalencia de síndrome metabólico fue mayor en las mujeres menopáusicas que en aquellas en la premenopausia. El principal factor de riesgo para el aumento de esta prevalencia fue la edad. La menopausia, cuando analizada aisladamente, no se constituyó un factor de riesgo para el síndrome metabólico.

Effect of cross-linking on corneal thickness in patients with corneal edema.

PURPOSE: To investigate the pachymetric changes of collagen cross-linking in corneas with edema because of endothelial dysfunction. METHODS: Interventional case series included 25 eyes of 25 consecutive patients with corneal edema for at least 4 months related to Fuchs endothelial dystrophy, corneal graft failure, and postoperative bullous keratopathy. Central corneal thickness was measured preoperatively, 1, 3, and 6 months after the procedure by ultrasound pachymetry and optical coherence tomography. RESULTS: Mean central corneal thickness measured by ultrasound pachymetry decreased after corneal cross-linking (mean +/- SD): 712.0 +/- 99.7, 618.3 +/- 103.0, and 657.5 +/- 114.8 for preoperative, 1-, and 3-month follow-up, respectively. Differences between preoperative value and 1- and 3-month follow-up values were statistically significant (P < 0.01). Similar results were found with the optical coherence tomography (mean +/- SD): 777.3 +/- 131.0, 711.6 +/- 133.1, 746.4 +/- 142.4, and 830.6 +/- 198.7, for preoperative, 1-, 3-, and 6-month follow-up values, respectively. Fourteen patients (56%) developed new epithelial bullae after 3 months; 11 patients (44%) remained asymptomatic until their last visit. CONCLUSION: Corneal cross-linking showed to be a safe procedure and potential therapeutic alternative for the treatment of corneal edema.

Effect of collagen cross-linking in stromal fibril organization in edematous human corneas.

PURPOSE: To assess structural stromal modifications after riboflavin and UV-A exposure in edematous human corneas. METHOD: Fourteen eyes with corneal edema were enrolled in the study. In the cross-linking (CXL) group, 7 corneal buttons were obtained from 6 patients who underwent penetrating keratoplasty (PK) 7-90 days after the CXL treatment. The control group was composed of 7 corneal buttons with bullous keratopathy. After the PK, stromal modifications were investigated using immunofluorescence in all corneal grafts. All patients had at least 3 months of corneal edema and were in the eye bank list waiting for keratoplasty. RESULTS: All corneas in the treated group showed a pronounced lamellar zone of collagen fibers highly organized in the anterior stroma, but there was not complete homogeneity between the samples. Corneas with advanced disease and stromal fibrosis were less compacted than ones with mild disease severity. Similarly, those ones that underwent PK 3 months after CXL also showed a decreased effect compared with those with a reduced time between the CXL and the PK. DAPI staining demonstrated a complete fragmentation of keratocytes nuclei in the anterior stroma in all treated corneas, which were absent in the control group. CONCLUSIONS: Our study showed an immediate effect of CXL with a limited long-term sustainability. Cross-linked corneas had a pronounced anterior zone of organized collagen fibers. Even the treated corneas with advanced bullous keratopathy and stromal fibrosis had histological evidence of collagen fibers organization, but this effect seems to be decreased compared with corneas in initial stages of the disease.

[Metabolic syndrome in outpatient cardiology clinics]. / Síndrome metabólica em ambulatório cardiológico.

BACKGROUND: In Brazil, the prevalence of the metabolic syndrome (MS) is little known in several regions. OBJECTIVE: To analyze the prevalence of MS, its components and the agreement between two diagnostic definitions in a population aged > 13 years. METHODS: Cross-sectional study conducted from June to October 2007 in 719 patients of outpatient cardiology clinics in the city of São Luis, State of Maranhão, Brazil. Blood pressure (BP), weight, height, waist circumference and lipid profile were measured. Risk factors for MS were evaluated according to the International Diabetes Federation (IDF) definition. Prevalence ratios and 95% confidence intervals were estimated using Poisson regression. RESULTS: The prevalence of MS was higher in both genders when using IDF definition (62.3% in men and 64.6% in women) than when using that of the National Cholesterol Education Program - Adult Treatment Prevention (NCEP ATPIII) (48.9% in men and 59% in women). The most prevalent MS components were: hypertension (87.2% and 86%); hypertriglyceridemia (84.4% and 82.5%); increased waist circumference (77.8% and 100%); low HDL-c (58.1% and 49.9%); and high blood glucose (59.9% and 51.9%), using NCEP ATPIII and IDF definitions, respectively. In the adjusted analysis, age > 60 years and body mass index (BMI) > 30 were associated with a higher risk of MS (p<0.001). CONCLUSION: The prevalence of MS was much higher than in the overall population, and hypertension was the most prevalent component. There was good agreement between the two definitions, very good in the female gender and moderate in the male gender.

Síndrome metabólica em ambulatório cardiológico / Metabolic syndrome in outpatient cardiology clinics / Síndrome metabólico en ambulatorio cardiológico

Fundamento: No Brasil, a prevalência de síndrome metabólica (SM) é pouco conhecida em várias regiões. Objetivo: Analisar a prevalência da SM, seus componentes e a concordância entre dois critérios diagnósticos numa população com idade > 13 anos. Métodos: Estudo transversal, realizado de junho a outubro de 2007, em 719 pacientes, em ambulatórios cardiológicos de São Luís, MA. Mediu-se a pressão arterial (PA), peso, altura, circunferência abdominal e perfil lipídico. Avaliaram-se os fatores de risco para a SM segundo o critério da International Diabetes Federation (IDF). Razões de prevalência e intervalos de confiança de 95 por cento foram estimados pela regressão de Poisson. Resultados: A prevalência da SM foi maior em ambos os sexos pelo conceito da IDF (62,3 por cento em homens e 64,6 por cento em mulheres), em relação ao do National Cholesterol Education Program - Adult Treatment Prevention (NCEP ATPIII) (48,9 por cento em homens e 59 por cento em mulheres). Os componentes da SM mais prevalentes foram: hipertensão arterial sistêmica HAS (87,2 por cento e 86 por cento); hipertrigliceridemia (84,4 por cento e 82,5 por cento); circunferência abdominal alterada (77,8 por cento e 100 por cento); HDL-c baixo (58,1 por cento e 49,9 por cento); e glicemia alterada (59,9 por cento e 51,9 por cento), pelos conceitos NCEP ATPIII e IDF, respectivamente. Após análise ajustada, idade > 60 anos e índice de massa corporal (IMC) > 30 foram associados a um maior risco de SM (p < 0,001). Conclusão: A prevalência da SM foi bem maior que a população geral; a (HAS) foi o componente mais prevalente. Houve boa concordância entre os dois critérios, sendo ótima no sexo feminino e regular no masculino.

Background: In Brazil, the prevalence of the metabolic syndrome (MS) is little known in several regions. Objective: To analyze the prevalence of MS, its components and the agreement between two diagnostic definitions in a population aged > 13 years. Methods: Cross-sectional study conducted from June to October 2007 in 719 patients of outpatient cardiology clinics in the city of São Luis, State of Maranhão, Brazil. Blood pressure (BP), weight, height, waist circumference and lipid profile were measured. Risk factors for MS were evaluated according to the International Diabetes Federation (IDF) definition. Prevalence ratios and 95 percent confidence intervals were estimated using Poisson regression. Results: The prevalence of MS was higher in both genders when using IDF definition (62.3 percent in men and 64.6 percent in women) than when using that of the National Cholesterol Education Program - Adult Treatment Prevention (NCEP ATPIII) (48.9 percent in men and 59 percent in women). The most prevalent MS components were: hypertension (87.2 percent and 86 percent); hypertriglyceridemia (84.4 percent and 82.5 percent); increased waist circumference (77.8 percent and 100 percent); low HDL-c (58.1 percent and 49.9 percent); and high blood glucose (59.9 percent and 51.9 percent), using NCEP ATPIII and IDF definitions, respectively. In the adjusted analysis, age > 60 years and body mass index (BMI) > 30 were associated with a higher risk of MS (p<0.001). Conclusion: The prevalence of MS was much higher than in the overall population, and hypertension was the most prevalent component. There was good agreement between the two definitions, very good in the female gender and moderate in the male gender.

Después del análisis ajustado, edad > 60 años e índice de masa corporal (IMC) > 30 se asociaron a un mayor riesgo de SM (p < 0,001). Conclusión: La prevalencia de SM fue mucho mayor que la población general; la HAS fue el componente más prevalente. Hubo buena concordancia entre los dos criterios, siendo óptima en el sexo femenino y regular en el masculino.

Effects of weight loss induced by bariatric surgery on the prevalence of metabolic syndrome.

BACKGROUND: Metabolic Syndrome (MS) is often linked to overweight/obesity and can improve after weight loss, such improvement is expected to be proportional to the intensity of weight loss. OBJECTIVE: The aim of this study was to evaluate the impact of weight loss induced by bariatric surgery (BS) on the prevalence of MS in a middle-term period. METHODS: Thirty-five (35) patients who underwent surgical Roux's Y gastrojejunal by-pass from October 2001 until October 2005 in our University Hospital were evaluated. 88.5% were female, with a mean age at the time of surgery of 37.8+/-11.1 years and a mean BMI of 45.0+/-6.2 Kg/m(2). During the first stage of our study demographic and clinical-anthropomorphic data were collected prior to the BC procedure, including those criteria needed for the diagnosis of MS, according to the guidelines of the US NCEP. The second stage consisted of reevaluation of those patients in the post-surgical period in order to determine the prevalence of MS in an outpatient setting. RESULTS: Prior to surgery, MS was diagnosed in 27 patients (77.1%). When those patients were reevaluated 34.4+/-15 months after surgery, a reduction of mean BMI to 28.3+/-5.0 Kg/m(2) and MS was identified in only two patients (5.7%) (p<0.001). Prevalence of individual criteria such as abdominal circumference, fasting glucose levels, arterial blood pressure, HDL-cholesterol and triglycerides had a reduction of 45.8%, 83%, 87.5%, 57.13% and 94% respectively. CONCLUSION: MS is a rather common feature in obese patients enrolled for BS and this procedure has been proved to be extremely efficient reversing the metabolic syndrome, with an expressive reduction of prevalence of each and all of the NCEP criteria.

Efeito da perda ponderal induzida pela cirurgia bariátrica sobre a prevalência de síndrome metabólica / Efecto de la pérdida ponderal inducida por la cirugía bariátrica sobre la prevalencia de síndrome metabólico / Effects of weight loss induced by bariatric surgery on the prevalence of metabolic syndrome

FUNDAMENTO: A síndrome metabólica (SM) está frequentemente ligada ao excesso de peso e melhora com a perda ponderal, sendo esperado que essa melhora seja proporcional à intensidade dessa perda. OBJETIVO: Avaliar o impacto da perda ponderal induzida pela cirurgia bariátrica (CB) sobre a prevalência da SM, em médio prazo. MÉTODOS: Foram analisados 35 pacientes submetidos à cirurgia de by-pass gastrojejunal em Y de Roux, no período de outubro de 2001 a outubro de 2005, em nosso HU, sendo 88,5 por cento do sexo feminino, com uma média de idade de 37,8±11,1 anos e um IMC médio de 45,0±6,2 kg/m². Na primeira etapa da pesquisa, foram obtidos dados demográficos e clínico-antropométricos antes da realização da CB, incluindo os critérios para o diagnóstico da SM, de acordo com as diretrizes do NCEP dos Estados Unidos. Na segunda etapa, os pacientes operados foram reavaliados ambulatorialmente quanto à prevalência da SM. RESULTADOS:Antes da cirurgia, a SM foi diagnosticada em 27 pacientes (77,1 por cento). Em reavaliação 34,4±15 meses após a cirurgia, observou-se uma queda do IMC médio para 28,3±5,0 kg/m² e a SM foi detectada em apenas dois pacientes (5,7 por cento) (p<0,001). A prevalência dos critérios cintura abdominal, glicemia, pressão arterial, HDL-colesterol e triglicerídeos foi reduzida em, respectivamente, 45,8 por cento, 83 por cento, 87,5 por cento, 57,13 por cento e 94 por cento. CONCLUSÃO: A SM é ocorrência comum em obesos candidatos à CB e esse procedimento se mostrou extremamente eficaz na indução da regressão da síndrome, verificando-se redução expressiva da prevalência de todos os critérios do NCEP.

Photorefractive keratectomy with mitomycin-C for consecutive hyperopia after radial keratotomy.

PURPOSE: To evaluate the safety, efficacy, and stability of excimer laser photorefractive keratectomy (PRK) and mitomycin-C (MMC) 0.02% for consecutive hyperopia after radial keratotomy (RK). METHODS: A prospective, nonrandomized, noncomparative interventional case series of 35 eyes (22 patients) with consecutive hyperopia after RK. All eyes were treated with PRK, using a single intraoperative topical application of MMC 0.02% for 60 seconds. Uncorrected visual acuity, best spectacle-corrected visual acuity, refraction, slit-lamp evidence of corneal haze, and endothelial cell counts were evaluated for up to 18 months after surgery. RESULTS: Postoperative follow-up was 9.6 +/- 5.5 months (ranged from 3 to 18 months). The mean spherical equivalent was +3.36 +/- 1.94 diopters preoperatively and +0.27 +/- 1.38 diopters 12 months after surgery. The uncorrected visual acuity was > or =20/30 in 37.1% of the eyes at 1 month and 78.6% of the eyes at 12 months. At 12 months, 14% of the eyes lost up to 1 line of Snellen acuity in the best spectacle-corrected visual acuity. No corneal haze was observed and the endothelial cell counts remained unchanged postoperatively (P > 0.05). CONCLUSION: PRK with MMC 0.02% for consecutive hyperopia after RK seems to be a safe and effective procedure at least in the short-term period of 6 months.

Prevalence of arterial hypertension and associated factors in adults in São Luís, state of Maranhão.

BACKGROUND: Little is known about the prevalence of arterial hypertension (AH) and its risk factors in the less developed regions of Brazil. OBJECTIVE: To estimate the prevalence of arterial hypertension and its associated factors in the population > 18 years in São Luís, state of Maranhão according to the Seventh Report of the Joint National Committee (JNC 7) criteria. METHODS: A cross-sectional study was conducted in São Luís, MA, from February to March 2003, with 835 individuals >18 years who completed a structured household questionnaire. Measurements of arterial pressure (AP), weight, height and waist circumference were taken, and other risk factors for cardiovascular disease were assessed. The Poisson regression method was used for the identification of factors associated with AH, with an estimate of the prevalence ratio (PR) and its corresponding 95% confidence interval. RESULTS: Age varied from 18 and 94 years (mean age was 39.4 years), 293 (35.1%) individuals were normotensive and 313 (37.5%) were pre-hypertensive. The AH prevalence was 27.4% (95% CI--24.4% to 30.6%), and it was higher among men (32.1%) than among women (24.2%). In the adjusted analysis, the following remained independently associated with AH: male gender (PR 1.52, 95% CI, 1.25-1.84), age > or = 30 years, with PR=6.65, 95% CI, 4.40-10.05 for > or = 60 years of age, overweight (PR 2.09 95% CI 1.64-2.68), obesity (PR 2.68, 95% CI, 2.03-3.53) and diabetes (PR 1.56, 95% CI, 1.24-1.97). CONCLUSION: These findings suggest the need to control overweight, obesity and diabetes, especially among women and individuals > or = 30 years of age in order to reduce the prevalence of arterial hypertension.

Prevalência da hipertensão arterial em adultos e fatores associados em São Luís - MA / Prevalence of arterial hypertension and associated factors in adults in São Luís, state of Maranhão

FUNDAMENTO: No Brasil, a prevalência de hipertensão arterial (HA) e seus fatores de risco são pouco conhecidos nas regiões menos desenvolvidas. OBJETIVO: Estimar a prevalência da hipertensão arterial na população > 18 anos em São Luís - MA e fatores associados, de acordo com os critérios do Seventh Report of the Joint National Committee (JNC 7). MÉTODOS: Realizou-se estudo transversal em São Luís - MA, de fevereiro a março de 2003, em 835 pessoas com idade > 18 anos que responderam a um questionário estruturado em domicílio. Foram medidos pressão arterial (PA), peso, altura e circunferência abdominal. Avaliaram-se outros fatores de risco para doença cardiovascular. Na identificação dos fatores associados à HA foi utilizado o modelo de regressão de Poisson, com estimativa da razão de prevalências (RP) e seu respectivo intervalo de confiança de 95 por cento. RESULTADOS: A idade variou entre 18 e 94 anos (média de 39,4 anos), sendo 293 (35,1 por cento) pessoas normotensas e 313 (37,5 por cento) pré-hipertensas. A prevalência de HA foi de 27,4 por cento (IC95 por cento 24,4 por cento a 30,6 por cento), maior no sexo masculino (32,1 por cento) que no feminino (24,2 por cento). Na análise ajustada permaneceram independentemente associados à HA: sexo masculino (RP 1,52 IC95 por cento 1,25-1,84), idade > 30 anos, sendo RP=6,65, IC95 por cento 4,40-10,05 para idade > 60 anos, sobrepeso (RP 2,09 IC95 por cento 1,64-2,68), obesidade (RP 2,68 IC95 por cento 2,03-3,53) e diabete (RP 1,56 IC95 por cento 1,24-1,97). CONCLUSÃO: Os resultados sugerem a necessidade de controle do sobrepeso, obesidade e diabete, sobretudo em mulheres e pessoas com idade maior ou igual a 30 anos para a redução da prevalência da hipertensão arterial.
