Abstract

Summary Methods The incidence of obesity is increasing worldwide, especially in countries with accelerated economic growth. We determined the prevalence of and associations between overweight/ obesity and cardiovascular risk factors in pre-pubertal (seven- to 11-year-old) schoolchildren (both genders, n = 198) in Luanda, Angola. Biochemical (fasting blood) and clinical examinations were obtained in a single visit. Data are reported as prevalence (95% confidence intervals) and association (r, Pearson). Results Prevalence of overweight/obesity was 17.7% (12.4–23.0%), high blood pressure (BP < 90% percentile) was 14.6% (9.7–19.5%), elevated glucose level was 16.7% (11.5–21.9%) and total cholesterol level < 170 mg/dl (4.4 mmol/l) was 69.2% (62.8–75.6%). Significant associations between body mass index (BMI) and systolic and diastolic BP (r = 0.46 and 0.40, respectively; p < 0.05) were found. No association between BMI and elevated glucose or cholesterol levels was found. Conclusion The prevalence of cardiovascular risk factors was high in pre-pubertal schoolchildren in Angola and fat accumulation was directly associated with blood pressure increase but not with other cardiovascular risk factors.

Abstract

Summary Background Levels of salt consumption and its awareness among medical students in Angola remain insufficiently studied. This study determined salt intake and assessed medical students’ knowledge, attitude and behaviour regarding salt consumption. Methods Were collected 24-hour urine samples from a random sample of 123 undergraduate medical students aged 17–43 years who were studying at the University of Agostinho Neto in Luanda. Their knowledge, attitude and behaviour regarding dietary salt were surveyed. Socio-demographic, clinical and anthropometric data were collected. Results Average salt intake was 14.2 ± 5.1 g/day, without significant difference between genders (p = 0.221). In total, 96.7% consumed over 5 g/day, but only 6.5% of participants were aware of their excessive salt intake. The majority knew about salt-related health consequences and 45.5% reported they controlled their salt intake. Conclusions This study indicated a high salt intake and inadequate behaviour regarding dietary salt consumption among medical students studying at the University of Agostinho Neto. This highlights the need for nutritional education to improve their dietary habits and future role in counselling.

Abstract

BACKGROUND To analyze the relationship between early-life indicators, blood pressure (BP), and arterial stiffness in childhood, in three samples with different bio-cultural characteristics. METHODS The total sample included 520 schoolchildren 9–10 years of age from Madrid (Spain), Vitória (Brazil), and Luanda (Angola). Height and weight, BP, and carotid-femoral pulse wave velocity (cf-PWV) were measured, all by one observer in each site, and body mass index (BMI) was calculated. Birth weight, gestational age, type of feeding, and age at weaning were extracted from official health cards. Data were analyzed by multiple linear regression models. RESULTS No significant differences were observed in systolic blood pressure (SBP) and diastolic blood pressure (DBP) among the samples (P = 0.107 and P = 0.808). Luanda showed the higher cf-PWV (5.7 m/s), followed by Vitória (5.3 m/s) and Madrid (4.9 m/s; P < 0.001). Explanatory factors for the observed variability in SBP, DBP, and cf-PWV, obtained by means of multiple linear regression models, were different in three samples. BMI showed a positive and significant association with SBP, DBP, and cf-PWV in three samples. In the Angolan sample, in addition to BMI, birth weight was maintained in the explanatory models of SBP and cf-PWV adjusted for BP, with a negative and significant coefficient (−0.019 and −0.019) CONCLUSIONS Higher values of BMI in childhood are related with higher values of cf-PWV, SBP, and DBP in the three samples. Children from Angola showed the highest mean value of cf-PWV, especially those who had lower birth weight, suggesting that worse conditions in fetal life may contribute to increased aortic stiffness in childhood.

12. Predictors and Reference Values of Pulse Wave Velocity in Prepubertal Angolan Children.

Author

Silva, Amílcar B.T., Capingana, Daniel P., Magalhães, Pedro, Molina, Maria del Carmen B., Baldo, Marcelo P., Mill, José Geraldo, Silva, Amílcar B T, Magalhães, Pedro, and Mill, José Geraldo

Abstract

Carotid-femoral pulse wave velocity (PWV) has been used as the gold standard method to estimate arterial stiffness. However, its use in clinical practice is still limited because reference values for specific groups, such as black children, remain unknown. The authors aimed to investigate predictors and to propose preliminary reference values of PWV in this population. Prepubertal schoolchildren (N=157; mean age, 9.36±1.41 year) from Luanda (Angola) with normal blood pressure values and without obesity were included. Mean PWV was 5.73±0.68 m/s, with no difference between the sexes. Univariate regression analysis showed a significant (P<.05) positive correlation between PWV and height, age, body weight, lean body weight, and blood pressure. In multivariate analysis, however, only height remained an independent predictor of PWV [PWV=0.018×height (cm)+3.230]. Curves of PWV percentiles as a function of height are proposed, thus identifying normal PWV in black children. [ABSTRACT FROM AUTHOR]

Abstract

Introdução: A influência da idade, duração da diabetes e da HbA1c sobre a motilidade do esfíncter esofágico inferior (EEI) na diabetes mellitus é mal conhecida. O objectivo é estudar a motilidade do EEI em diabéticos tipo 2. Material e método: Avaliou&-se, por manometria esofágica, a motricidade do EEI a 36 diabéticos de ambos géneros (39-81 anos). Apresentam-se a média ± erro padrão. Resultados: Nos diabéticos 60 anos foram semelhantes os valores da Pressão Basal do EEI = (PBEEI), relaxamento do EEI = (%REEI), duração do relaxamento (DREEI), relaxamento completo = (RC), parcial = (RP) ou ausência de relaxamento (RA) do EEI. Os diabéticos há mais de 10 anos tiveram maior % REEI 7,1 ± 4,1 que os há 10 ou menos anos 66,3 ± 2,7; p < 0,04. Comparando os grupos HbA1c 7 mmol/l verificou-se que a PBEEI 23,4 ± 2,03 vs 18.38 ± 1,01; p < 0,02 e o RC 54,93 ± 9,6 vs 27,38 ± 5,2 mmHg; p < 0,02 foram maiores nos indivíduos com HbA1c 0,05). Conclusões: 1-A idade não influenciou significativamente a motilidade do EEI. 2-A %REEI foi maior nos diabéticos há mais de 10 anos. 3-Os diabéticos com HbA1c 60 years old), the basal pressure, percentage of relaxation (%), relaxation duration, the complete (CR), partial (PR) and absent (AR) relaxation of the were similar. Patients with over 10 years of diabetes had higher % 77.1±4.1 than those with 10 years or less 66.3±2.7; P0.05). Conclusion: 1- The age didn’t influence the motility of the IES. 2- The %RLES was higher in patients with over 10 years of diabetes. 3- Diabetics with HbA1c

Abstract

The Sclerosing Mesenteritis is a rare idiopathic disease. It represents the final stadium of progression of the chronic inflammatory illnesses of the intestinal mesentery, with predominance of fibrosis. The clinical manifestations are varied and unspecific. Diagnosis, that demands high degree of suspicion, can be presumed for imaging study, that discloses heterogeneous mass with tumor-like appearance, and confirmed on the basis of anatomo-pathological examination. The treatment is empirical and the prognostic is habitually favourable, over all in initial stadiums of the illness, being in a minority fatal. The authors describe the clinical case of a 50 years-old woman, admitted in the hospital for abdominal pain, ascitis and fever and that by radiological suspicion of peritoneal carcinomatosis and negative complementary study for primitive neoplasm, was submitted to an exploring laparotomy. Observed accented thickening of the mesentery that formed an extensive adherent conglomerate of bowel loops, whose biopsy had disclosed to be a sclerosing mesenteritis. Was verified an irrelevant answer to the treatment and an unfavourable, lethal, clinical course. The authors provide a literature review concerning the most relevant aspects of this disease.
