Abstract
BACKGROUND Religiosity and spirituality have been associated with higher recovery rates, greater adherence to treatments, and better levels of quality of life in patients with heart disease. OBJECTIVES To evaluate the association between spirituality, functional gain, and improved quality of life in patients in a cardiovascular rehabilitation program. METHODS This prospective cohort study evaluated the association between functional and quality of life gains during a cardiovascular rehabilitation program and a religiosity/spirituality index based on a validated scale. Depression, anxiety, and stress symptoms were screened for control purposes. P values < 0.05 were considered significant for all analyses. RESULTS The study followed 57 patients (66 ± 12 years old; 71.7% male; 76% with coronary artery disease). The Spearman correlation coefficient did not show any associations between increases in functional capacity and organizational (rs = 0.110; p = 0.421), non-organizational (rs = -0.007; p = 0.421), or intrinsic (rs = -0.083; p = 0.543) religiosity. Furthermore, no associations were detected between the results of a quality of life score and organizational (rs = 0.22; p = 0.871), non-organizational (rs = 0.191; p = 0.159), or intrinsic (rs = 0.108; p = 0.429) religiosity. CONCLUSION No association was detected between functional and quality of life gains and organizational, non-organizational, or intrinsic religiosity in this sample of patients undergoing cardiovascular rehabilitation.

Urbanization and cardiovascular health among Indigenous groups in Brazil. COMMUNICATIONS MEDICINE 2023; 3:17. [PMID: 36732348 PMCID: PMC9895427 DOI: 10.1038/s43856-023-00239-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Accepted: 01/06/2023] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND We described the prevalence of cardiovascular risk factors in groups of Brazilian Indigenous people at different degrees of urbanization. METHODS The Project of Atherosclerosis among Indigenous populations (Projeto de Aterosclerose em Indígenas; PAI) is a cross-sectional study conducted in Northeast Brazil between August 2016-June 2017. It included three populations: Fulni-ô Indigenous people (lowest degree of urbanization), Truká Indigenous people (greater urbanization), and a highly urbanized non-Indigenous local cohort (control group). Participants were assessed to register sociodemographic, anthropometric, as well as clinical and laboratory-derived cardiovascular (CV) risk parameters. Age-adjusted prevalence of hypertension was also computed. Nonparametric tests were used for group comparisons. RESULTS Here we included 999 participants, with a predominance of females in all three groups (68.3% Control group, 65.0% Fulni-ô indigenous group, and 60.1% Truká indigenous group). Obesity was present in 45.6% of the urban non-Indigenous population, 37.7% Truká and in 27.6% Fulni-ô participants. The prevalence of hypertension was 29.1% (n = 297) with lower prevalence in the less urbanized Fulni-ô people (Fulni-ô - 18.2%; Truká - 33.9%; and Control - 33.8%; p < 0.001). In the elderly male population, the prevalence of hypertension was 18.7% in the Fulni-ô, 45.8% in the Truká, and 54.5% in the control group. Of the 342 participants that self-reported hypertension, 37.5% (n = 68) showed uncontrolled blood pressure (BP). Uncontrolled BP was more prevalent among Truká people when compared to Fulni-ô people and non-Indigenous participants (45.4%, 22.9%, and 40.7%, respectively; p < 0.001). CONCLUSIONS We found a higher cardiovascular risk in communities with a higher degree of urbanization, suggesting that living in towns and cities may have a negative impact on these aspects of cardiovascular health.

Lower Levels of Vitamin D Are Associated with an Increase in Insulin Resistance in Obese Brazilian Women. Nutrients 2021; 13:2979. [PMID: 34578857 PMCID: PMC8471993 DOI: 10.3390/nu13092979] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 08/18/2021] [Accepted: 08/24/2021] [Indexed: 12/12/2022] Open
Abstract
Adult women are more likely to be obese than men. Moreover, there is evidence that obesity is a risk factor for increased insulin resistance (IR) and hypovitaminosis D (VITD), conditions related to metabolic and endocrinologic disturbance. We performed a cross-sectional study with 103 women diagnosed with obesity, recruited between 2009 and 2013, in an obesity referral outpatient clinic in Bahia, Brazil. Laboratory and clinical characteristics were compared between the groups according to the degree of obesity (I, II and III), and levels of 25-hydroxyvitamin D [25(OH)D] were used to define the VITD status (insufficiency and no insufficiency). We calculated the homeostatic model assessment-IR (HOMA-IR) index to assess insulin resistance in the groups. Our analyses revealed that HOMA-IR values and VITD levels were inversely correlated. Furthermore, we observed a distinct expression profile of values of laboratory markers according to 25(OH)D levels. Negative correlations were found between HOMA-IR and body mass index (BMI) in VITD insufficient participants but not in those with the sufficiency. Furthermore, multivariate regression demonstrated independent associations between lower levels of 25(OH)D and increased values of HOMA-IR. These findings suggests that lower levels of VITD are strongly associated with the increased IR in obese women.

Abstract
BACKGROUND A randomized, parallel-controlled, blinded clinical trial was conducted to evaluate the effect of Healing Meditation on stress and eating behavior of women undergoing standard weight-loss treatment. MATERIALS AND METHODS An outpatient clinic in Brazil, 55 women with overweight and obesity were included and randomized: 27 for the Meditation Group, and 28 for the Control Group. Randomization was stratified by body mass index category and based on blocks of four. For eight weeks, in addition to the standard weight loss treatment, the Intervention Group underwent a Healing Meditation program, and the Control Group participated in a round table to observe compliance. Reduction in stress and changes in eating behavior were assessed at baseline, and in the 8th, and 16th week using the Perceived Stress Scale, the Dutch Eating Behavior Questionnaire, and Binge Eating Scale. RESULTS The sample mean age was 49 ± 11 years, 72.7% were obese, with a predominance of mixed (49.1%) and black (41.8%) ethnicity. After eight weeks, the Meditation Group showed a mean reduction in total stress of -17.4 (IC 95% -19.5 to -15.3 p < 0.001). In eating behavior, a mean reduction of -7.9 (p < 0.001) in external eating, of -11.4 (p < 0.0001) in emotional eating, and a rise of 9.6 (p < 0.0001) in restrained eating were found. Score levels remained stable between the 8th and 16th week. Binge eating had a mean variation of -22.2%(p = 0.011). CONCLUSION The addition of Healing Meditation to the standard weight-loss treatment may significantly reduce stress and produce positive changes in the eating behavior of overweight and obese women.

Hydroxyurea treatment is associated with reduced degree of oxidative perturbation in children and adolescents with sickle cell anemia. Sci Rep 2020; 10:18982.

Abstract
Sickle cell anemia (SCA) is the most common inherited hemolytic anemia worldwide. Here, we performed an exploratory study to investigate the systemic oxidative stress in children and adolescents with SCA. Additionally, we evaluated the potential impact of hydroxyurea therapy on the status of oxidative stress in a case–control study from Brazil. To do so, a panel containing 9 oxidative stress markers was measured in plasma samples from a cohort of 47 SCA cases and 40 healthy children and adolescents. Among the SCA patients, 42.5% were undertaking hydroxyurea. Multidimensional analysis was employed to describe disease phenotypes. Our results demonstrated that SCA is associated with increased levels of oxidative stress markers, suggesting the existence of an unbalanced inflammatory response in peripheral blood. Subsequent analyses revealed that hydroxyurea therapy was associated with diminished oxidative imbalance in SCA patients. Our findings reinforce the idea that SCA is associated with a substantial dysregulation of oxidative responses which may be dampened by treatment with hydroxyurea. If validated by larger prospective studies, our observations argue that reduction of oxidative stress may be a main mechanism through which hydroxyurea therapy attenuates the tissue damage and can contribute to improved clinical outcomes in SCA.

Abstract
Objective: To evaluate the effect of healing meditation on weight loss and waist circumference for women undergoing a standard weight loss treatment. Design: We conducted a randomized, parallel-controlled, blinded clinical trial. Randomization was stratified by body mass index category and based on blocks of four. Setting: An outpatient clinic in Brazil. Subjects: Women with overweight and obesity. Intervention: For 8 weeks, in addition to the standard weight loss treatment, the intervention group underwent a healing meditation program, and the control group participated in a two round table just to observe the treatment compliance. Outcome measures: The primary outcome was the percentage of weight loss, blindly assessed regarding the allocation group. Results: Of 121 women interested in participating in the study, 55 were included and randomized, 27 for the intervention group and 28 for the control group. Baseline characteristics were similar between groups. After 8 weeks, the intervention group had the highest relative reduction to initial body weight (-2.9% [interquartile range {IQR} -4.4 to -1.6] vs. -0.7% [IQR -1.1 to -5.0], p < 0.001). Waist circumference outcome was also significantly reduced in the intervention group (5 cm [IQR -6.0 to 4.0] vs. -1 cm [IQR -2.0 to 0.0], p < 0.001). The result of the intervention group was maintained until the 16th week. Between 8th and 16th week, the control group underwent meditation and presented significant weight reduction (-1.95 kg [IQR -3.2 to -1.1], p < 0.001 and -2.3% [IQR -4.1 to -1.3], p < 0.001), showing similar effect to the intervention group (p = 0.428). Conclusion: The addition of healing meditation to the standard weight loss treatment may reduce weight and waist circumference over a short period in overweight or obese women.

Abstract
Background There are various factors that influence the effect of physical exercise on the lipid profile, among them the body mass index and calorie expenditure of the exercise are some of the main factors. To test the hypothesis that a physical exercise session based on caloric expenditure may acutely modify the glycemia and lipid values of women with excess body mass. Methods The study included 66 women, randomly divided into two groups, control and experimental, with BMI of 29 ± 4.4 kg/m2 vs 29 ± 4.3 kg/m2 (p = 0.45) sedentary and aged 23 ± 3.8 vs 24 ± 3.5 years, respectively (p = 0.25). After 12 h fasting, the volunteers underwent the first blood collection. The experimental group was submitted to a physical exercise session corresponding to energy expenditure of 250Kcal, of light intensity based the Borg Rating of Perceived Exertion (RPE), 12 h after the first blood collection. The control and experimental group volunteers underwent a second blood collection 24 h after the first. Glycemia, insulin status and lipid profile were measured and Homa IR and Homa-beta were calculated. The t-test for independent and dependent samples was used, and a level of significance of 5% was adopted. Results Physical exercise changed the glycemic response in both the intragroup analysis (before = 96 ± 6.6 mg/dL vs after = 92 ± 6.6 mg/dL), (p = 0.01), and in the intergroup analysis (control = Δ 0.9 ± 6.1 vs experimental = Δ -4.1 ± 6.3) (p = 0.02). No changes were shown for the Homa IR, Homa Beta and Insulin indexes. When the lipid profiles were evaluated, differences in HDL were shown in the intragroup analysis (before = 89 ± 10.5 mg/dL vs. after = 91 ± 10.3 mg/dL) (p = 0.04). For the other parameters (LDL, TG, Total Cholesterol, TG/HDL), no changes were shown. Conclusion In women with excess body weight, a low intensity exercise session diminished the glycemia, but did not change the lipid response. Trial registration NCT03170973. Retrospectively registered.

Abstract
OBJECTIVE To evaluate the association between endothelial dysfunction and otoneurological symptoms and vaso-occlusive phenomena in children with sickle cell disease (SCD). METHODS Cross-sectional study with 54 children, aged between 6 and19 years of age, of whom 28 had genotype SS and 26 apparently healthy (AA genotype) whose parents or guardians, or the children themselves, filled out a questionnaire designed to assess their otoneurological symptoms. All the individuals were submitted assessment of endothelial function by flow-mediated dilation (FMD) percentage with reactive hyperemia of brachial artery Doppler. RESULTS Otoneurological symptoms (tinnitus and/or vertigo) predominated in the SCD group (46.4 vs. 15.4%; p = 0.006). A negative correlation was observed between FMD percentage and time of evolution of vertigo SCD (r = -0.432; p = 0.022) and the linear regression analysis demonstrated that for every reduction in FMD percentage there was an increase in time of evolution of vertigo of 1.79 months (β = -1.79; p = 0.022). The positive correlation between episodes of painful crisis and time of evolution of vertigo (r = 0.3; p = 0.04). DISCUSSION The presence of vascular endothelial damage in the labyrinthine artery in patients with SCD is capable of compromising the semicircular canals, shown by clinical expression of otoneurological symptoms, such as vertigo. In the present study, an association was observed between endothelial dysfunction with otoneurological symptoms and otoneurological symptoms and vaso-occlusive phenomena in SCD.

Abstract
Patients with diabetes mellitus are at high risk of developing atherosclerosis, associated with higher rates of micro and macro vascular involvement such as coronary artery disease and renal disease. The role of hyperglycemia to induce synthesis of reactive oxygen species by the oxidation of glucose, leading to an increased production of advanced glycosylation end products, as well as inflammation and oxidative stress has been proposed as a possible mechanism in the pathogenesis of endothelial dysfunction (ED). The interaction between C-peptide - the connecting segment of pro-insulin-and nitric oxide in vasodilation is also discussed. Therefore, endothelial dysfunction has been identified as an early marker of vascular disorder in type 1 and type 2 diabetes mellitus. In some other diseases, ED has been considered an independent predictor of vascular disease, regardless of the method used. Studies have demonstrated the importance of endothelial dysfunction as an useful tool for identifying the risk of vascular complications in patients with type 1 diabetes mellitus, particularly as regards to renal impairment. The aim of this review is to clarify the prognostic value of endothelial dysfunction as a marker of vascular disease in these subjects.

Abstract
Background To evaluate the effect of magnesium (Mg) replacement on insulin resistance and cardiovascular risk factors in women with metabolic syndrome (MS) without diabetes. Methods This 12-week clinical randomized double-blind study compared the effects of 400 mg/day of Mg with those of a placebo (n = 72) on fasting glucose, insulin, HOMA-IR, lipid profile and CRP. Mg was measured in serum (SMg) and in mononuclear cells (MMg). Results Hypomagnesemia (SMg < 1.7 mg/dL) was seen in 23.2% of patients and intracellular depletion in 36.1% of patients. The MMg means were lower in patients with obesity (0.94 ± 0.54 μg/mg vs. 1.19 ± 0.6 μg/mg, P = 0.04), and insulin resistance (0.84 ± 0.33 μg/mg vs. 1.14 ± 0.69 µg/mg, P < 0.05). Mg replacement did not alter SMg (1.82 ± 0.14 mg/dL vs. 1.81 ± 0.16 mg/dL, P = 0.877) and tended to increment MMg (0.90 ± 0.40 μg/mg vs. 1.21 ± 0.73 μg/mg, P = 0.089). HOMA-IR did not alter in interventions nor in placebo group (3.2 ± 2.0 to 2.8 ± 1.9, P = 0.368; 3.6 ± 1.9 to 3.2 ± 1.8, respectively), neither did other metabolic parameters. Conclusion Serum and intracellular Mg depletion is common in patients with MS; however, Mg replacement in recommended dosage did not increase significantly Mg levels, neither reduced insulin resistance or metabolic control.

Abstract
Background Obesity is a complex and multifactorial disease, has an inflammatory pattern and is associated with higher cardiometabolic risk. There are recent reports associating an elevated C-Reactive Protein (CRP) with a microscopic endothelial dysfunction. The objective is to evaluate if there is an association between serum levels of CRP and endothelial function in women with overweight/obesity, as well as the correlation between CRP and anthropometric variables. Methods This is a cross-sectional study that analyzed secondary data from patients treated in an institution of tertiary education, as part of the weight excess and cardiometabolic disease survey. The study included patients with overweight/obesity who had CRP and endothelial function tests already made and inserted into the survey database. The endothelial function was evaluated by: reactive hyperemia test (endothelium-dependent vasodilation). All tests were recorded and later analyzed by the same echocardiographer who performed the examination. Statistical analyses were realized in the Statistical Package for the Social Sciences (SPSS) version 14. It was considered statistically significant a P value < 0.05. Results This study included 47, nonsmoker women. with a BMI of 32.37 ± 5.06 kg/m2, median of CRP of 2.59 mg/L and flow-mediated dilation (FMD) of 8.75% ± 5.22%. There was no correlation between CRP and endothelial dysfunction in this population (rs = 0.08, P = 0.64). No correlation was observed between CRP and BMI. There were no differences of endothelial dysfunction variables and CRP in groups in use or not of medications (Hypolipidemic, antihypertensives and hypoglycemic agents). Conclusion There was no association between CRP and FMD and this can suggest that it is possible that the level of eNOS dysfunction associated with increased CRP is not enough to lead to macroscopic changes and harm vasodilation.

Abstract
BACKGROUND AND OBJECTIVES Due to the high prevalence of hypertension, the increase in life expectancy, and improvement of diagnostic methods and surgical techniques, this comorbidity will be increasingly more common in surgical patients. The objective of this study was to evaluate the behavior of the hemodynamic variables during anesthetic induction in treated hypertensive patients. METHODS This is an observational study on the behavior of hemodynamic parameters (systolic blood pressure, diastolic blood pressure, and heart rate) during the anesthetic induction of hypertensive and normotensive patients scheduled for elective surgeries under general anesthesia, at four moments: preparation (MP), drug (MD), laryngoscopy/intubation (ML), and 5 minutes after laryngoscopy/intubation (ML5). RESULTS The sample was composed of 128 patients divided into two groups: hypertensive (GH) and normotensive (GN). Diastolic blood pressure was reduced at MD in both groups, with a smaller percentage reduction in GH (18.3 +/- 14.0% versus 23.0 +/- 11.4%, p = 0.04). There was an increase in SBP and DBP at ML in both groups, with smaller percentage reductions in GH (8.2 +/- 16.3% versus 18.2 +/- 21.2%, p < 0.01; 8.6 +/- 20.2% versus 25.0 +/- 27.9%, p < 0.01, respectively for DBP and SBP). As for ML5, HR, SBP and DBP did not show significant differences between both groups. CONCLUSIONS Hypertensive patients under treatment and with controlled blood pressure levels demonstrated greater hemodynamic stability during anesthetic induction.

[PMID: 17884342 DOI: 10.1016/j.nut.2007.08.013] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2007] [Revised: 08/20/2007] [Accepted: 08/21/2007] [Indexed: 11/26/2022]
Abstract
OBJECTIVE The literature on palm oil as a cholesterol-raising oil is conflicting, requiring further studies. This study tested the influence of a palm oil-rich diet on plasma lipids of healthy young individuals. METHODS Thirty-four medical students, 18-26 y old, with a total cholesterol level <200 mg/dL, high-density lipoprotein cholesterol (HDL-C) level >40 mg/dL, low-density lipoprotein cholesterol (LDL-C) level <130 mg/dL, triacylglycerol level <150 mg/dL, glycemic level <100 mg/dL, blood pressure <140/90 mmHg, and a body mass index of 18 to <25 kg/m(2) were studied. Once a day for 2 wk, the students ingested 10 mL of previously boiled crude palm oil after lunch or dinner, as preferred. Palm oil was consumed in the same way and quantity that it is consumed in one serving of a very popular typical Brazilian seafood dish. Total cholesterol, LDL-C, HDL-C, very LDL-C, non-HDL-C, and triacylglycerol were measured at baseline, after the palm oil-enriched diet, and after the washout period. RESULTS A decrease in all lipid fractions was observed, with a mild, statistically significant decrease in concentrations of very LDL-C (19.41 +/- 4.21 versus 17.18 +/- 4.0 mg/dL, P = 0.002) and triacylglycerol (97.07 +/- 21.08 versus 85.91 +/- 20.02 mg/dL, P = 0.002). Males (61.9%) also showed a mildly significant increase in LDL-C, whereas females showed a mildly significant decrease in all lipid fractions, except for HDL-C. CONCLUSION This study shows that boiled crude palm oil may have a mild, triacylglycerol-reducing effect in young, healthy individuals and may also show a mild LDL-C-increasing effect in males.

Abstract
Antiretroviral therapy (ART) in HIV-infected patients has been associated with an increased risk of cardiovascular disease. This study evaluates vascular endothelial dysfunction of the peripheral circulation in Brazilian HIV-infected subjects on ART or naive to ART compared to a control group matched for age and body mass index (BMI). We performed a cross-sectional comparative study to measure postischemic peak flow-mediated dilation (FMD) of the brachial artery and the response to glyceryl trinitrate (GTN) in HIV-infected patients and healthy controls in Salvador, Bahia, Brazil. Endothelial vasomotor function was evaluated by assessing brachial artery FMD. Forty-four HIV-infected individuals (33 ARV treated and 11 ART naive) were compared to 25 healthy controls matched for age and BMI. FMD % was significantly lower for the ART-experienced patients compared to the ART-naive patients and was also significantly different from controls (ART experienced 8.2 +/- 6.0% vs. 19.3 +/- 4.8% vs. 23.3 +/- 6.1%), respectively (p < 0.0001). The cholesterol, triglyceride, and ALT levels were significantly higher in the ART-experienced group compared to the ART-naive and control subjects (p < 0.028); however, linear regression analysis revealed a statistically significant association of endothelial dysfunction as a dependent variable only with ARV treatment in HIV-infected subjects (p = 0.03). The association of endothelial dysfunction with ARV therapy in HIV-infected patients was independent of protease inhibitor-containing regimens or dyslipidemia. This dysfunction may contribute to the risk for HIV-associated atherosclerosis.

Abstract
Data on dyslipidemia in type 1 diabetes is scarce. The authors aimed to evaluate the lipid profile in patients with type 1 diabetes and its correlation to glycemic control. Ninety-four subjects (53.2% males), aged 15.4+/-4.7 (3.6-21.9 years), with disease duration of 5.0+/-3.6 years (0.3-17 years) were evaluated for heart rate, blood pressure, height, and weight. Laboratory data included total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides (TGs), glycemia, glycosylated hemoglobin (HbA1c), creatinine, thyroid-stimulating hormone, antithyroid antibodies, and 24-hour microalbuminuria. Correlations were performed by the Spearman rank correlation test, and the significance level was <0.05. Mean values were TC, 168.6+/-46.6 mg/d; HDL, 43.1+/-15.3 mg/dL; LDL, 110.9+/-40.6 mg/dL; TGs, 78.3+/-48.6 mg/dL; glycemia, 204.6+/-116.7 mg/dL; and HbA1c, 11.2%+/-2.9%. High TC (43.9% vs. 10.7%; p<0.002) and LDL (51.5% vs. 10.7%; p<0.01) were more prevalent in patients 19 years and younger (n=66). HbA1c correlated with TC (r=0.30; p=0.004), LDL (r=0.28; p=0.008), TG (r=0.31; p=0.003), and TG/HDL ratio (r=0.25; p=0.01). Duration of diabetes correlated with LDL (r=0.21; p=0.04) and insulin daily doses with TG (r=0.23; p=0.04) and body mass index expressed as z scores (r=-0.28; p=0.007). There was a high prevalence of hypercholesterolemia (54.6%) in these diabetic patients, and lipid fraction levels were correlated with HbA1c. Good management of diabetes seems to be of paramount importance in controlling dyslipidemia.

Abstract
OBJECTIVE To assess the frequency of cardiovascular risk factors in the rural community of Cavunge, in the Brazilian state of Bahia. METHODS A cross-sectional study was carried out with 160 individuals (age>19 years) randomly drawn from those listed in the population census of the Cavunge Project. The following parameters were studied: arterial hypertension, dyslipidemia, diabetes, obesity, smoking, waist-hip ratio (WHR), physical activity, and overall cardiovascular risk classified according to the Framingham score. The assessing parameters used were those established by the III Brazilian Consensus on Hypertension and the II Brazilian Consensus on Dyslipidemia. RESULTS Of the randomly drawn individuals, 126 with a mean age of 46.6 +/- 19.7 years were included in the study, 43.7% of whom were males. The frequency of arterial hypertension was 36.5%; 20.4% of the individuals had cholesterol levels > or =240 mg/dL; 31.1% of the individuals had LDL-C levels >130 mg/dL; 4% were diabetic; and 39.7% had a high-risk Framingham score. Abdominal obesity was observed in 41.3% of the population and in 57.7% of the females. High caloric-expenditure (HCE) physical activities were performed by 56.5% of the individuals. The HCE group had a greater frequency of normal triglyceride levels (63% vs 44%; P=0.05), no diabetes, and WHR tending towards normal (46% vs 27%, P=0.08) as compared with those in the low caloric-expenditure group. CONCLUSION Cardiovascular risk factors, such as hypertension and hypercholesterolemia, are frequently found in rural communities. The greatest frequency of normal triglyceride levels and normal WHR in the HCE group reinforces the association between greater caloric expenditure and a better risk profile.

Abstract
Control of risk factors for coronary heart disease secondary prevention is still very unsatisfactory. This study assessed 104 patients referred by cardiologists to discover how carefully National Cholesterol Education Program II recommendations were being followed. Average age of the cohort was 60.9+/-10.8 years, and 67.3% were men. A total of 57(54.8%) experienced a previous myocardial infarction and 83 (80.3%) a revascularization procedure. They saw their doctors 4.4+/-2.9 times a year and had blood tests 2.8+/-1.7 times a year. Blood pressure was >/=140/90 mm Hg in 57.8%, body mass index >/=25 kg/m2 in 62.5%, and the weight-to-hip ratio >/=0.95 in 42.9% of men, and >/=0.85 in 47.0% of women. Total, low-density lipoprotein, and high-density lipoprotein cholesterol and triglyceride values were 222.9+/-47.3 mg/dL, 144.9 mg/dL, 44.8+/-11.5 mg/dL, and 176+/-119.41 mg/dL, respectively. Low-density lipoprotein cholesterol was <100 mg/dL in 8.1%, and <130 mg/dL in 47.1%; the total cholesterol/high-density lipoprotein cholesterol ratio was 5.1+/-1.5 (>/=5 in 51%). In these patients, the control of major risk factors like high blood pressure, overweight, and high low-density lipoprotein cholesterol was poor.

Abstract
PURPOSE To correlate lipid profile with coronary artery disease (CAD). METHODS One hundred patients with symptoms of CAD were studied by coronariography: 62 males (55.6 +/- 9.26 years) and 38 females (56.3 +/- 9.72 years). Blood glucose, total cholesterol (TC), triglycerides (TG), and HDL-C (n = 96) levels were determined; LDL-C was calculated by the Friedewald formula. Coronary artery stenotic and normal proximal lumen were measured with a pachymeter, and the percent degree of obstruction calculated. The proximal, medial and distal segments of left anterior descending (LAD), circumflex (CX), right coronary artery (RCA) and the coronary trunk, 1st LAD diagonal branch and 1st RCA marginal branch were analysed. RESULTS Coronariography: CAD was documented in 74 patients, (56-75.6% men), with > or = 50% stenosis in 67 (90.5%), 54 (79.1%) men. The lesions were univessel in 24 (33.4%), bivessel in 29 (39.7%), and trivessel in 20 (27.4%). Seventy patients had TC > or = 200 mg/dl, 29 (41.4%) > or = 240 mg/dl); 69 (71.9%) LDL-C > or = 130 mg/dl, 37 (38.5%) > or = 160 mg/dl; 35 (36.5%) HDL-C < 35 mg/dl and 10 TG > or = 200 mg/dl. Lipid profile vs CAD -1) CAD patients had lower HDL-C values (38.8 +/- 10 mg/dl vs 48.2 +/- 13.6 mg/dl, p = 0.01) and higher Castelli risk indexes (CRI) (TC/HDL-C = 5.9 +/- 1.7 vs 5.1 +/- 1.4 and LDL-C/HDL-C = 4.1 +/- 1.5 vs 3.4 +/- 1.2, p = 0.04); 2) > or = 50% stenosis and multivessel disease showed higher CRI (p = 0.01 and p = 0.04 for TC/HDL-C, and p = 0.01 and p = 0.02 for LDL-C/HDL-C, respectively). Twenty one (70%) of the 30 patients with TC < 200 mg/dl had CAD (28% of the patients with CAD), in whom there was a high frequency of patients with a low HDL-C level (11/21, 52.4% vs 3/9, 33%, p = 0.06). CONCLUSION Lower HDL-C and higher CRI values were associated with more severe and intensive CAD; TC < 200 mg/dl is compatible with CAD, specially if there is a low HDL-C level. These findings strengthen the need of HDL-C measurement for CAD risk assessment.

[Perforation-dilatation of pulmonary atresia with intact interventricular septum in neonates and infants]. ARCHIVES DES MALADIES DU COEUR ET DES VAISSEAUX 1993; 86:581-6.

Abstract
Sixteen children (14 neonates less than 1 week old and 2 infants aged 3 and 6 months) had a "favorable" type of pulmonary atresia with an intact interventricular septum in which the hypoplasia of the right ventricle was mild and the cavity tripartite with a well developed infundibulum arriving in contact with a good-sized pulmonary artery from which it was separated by a totally or almost totally imperforate dome. They underwent a procedure associating an infusion of prostaglandin. E1 and an attempted pulmonary valve disobliteration by interventional catheterisation: needle puncture followed by balloon dilatation. There were 4 failed procedures (impossible puncture or dilatation), only one of which in the last 10 cases. The outcome of the 12 primary successes was related to the rapidity of recovery of right ventricular diastolic function: 7 patients were cured within a few days or weeks with prostaglandin therapy: 5 children required surgical anastomosis with a longer recovery period--3 cures but 2 deaths. Overall, there were two myocardial effractions without serious complications and 1 enterocolitis which was long-lasting but eventually cured. Two mild residual stenoses were redilated. In conclusion, the puncture-dilatation technique may be used instead of surgical valvectomy in favorable forms of pulmonary atresia with intact septum in the neonate. With experience, it was possible to remove the obstruction in 9 out of 10 cases with a minimum of complications. It is the compulsory first stage to complete cure, the probability and rapidity of which depend on recovery of right ventricular compliance.
