Obesity and lung function: a systematic review.

Obesity is a chronic disease characterized by the excessive accumulation of body fat that is harmful to the individuals. Respiratory disorders are among the comorbidities associated with obesity. This study had the objective of investigating the alterations in respiratory function that affect obese individuals. A systematic review was performed, by selecting publications in the science databases MEDLINE and LILACS, using PubMed and SciELO. The articles that assessed pulmonary function by plethysmography and/or spirometry in obese individuals aged under 18 years were included. The results demonstrated that the obese individuals presented with a reduction in lung volume and capacity as compared to healthy individuals. Reduction of total lung capacity and reduction of forced vital capacity, accompanied by reduction of the forced expiratory volume after one second were the most representative findings in the samples. The articles analyzed proved the presence of a restrictive respiratory pattern associated with obesity.

A obesidade é uma doença crônica, caracterizada pelo acúmulo excessivo de gordura corporal, que ocasiona prejuízos ao indivíduo. Dentre as comorbidades associadas à obesidade, estão as disfunções respiratórias. O presente estudo teve por objetivo investigar as alterações da função pulmonar que acometem indivíduos obesos. Foi realizada uma revisão sistemática, por meio da seleção de publicações nas bases científicas de dados MEDLINE e LILACS, por meio do PubMed e SciELO. Foram inclusos os trabalhos que avaliaram a função pulmonar, por meio de pletismografia e/ou espirometria, em indivíduos obesos maiores de 18 anos. Os resultados demonstraram que os indivíduos obesos apresentaram redução dos volumes e capacidades pulmonares quando comparados a indivíduos eutróficos. Redução da capacidade pulmonar total e redução da capacidade vital forçada, acompanhadas de redução do volume expiratório forçado após um segundo, foram os achados mais representativos dentre as amostras. Os trabalhos analisados comprovam a presença de padrão respiratório restritivo associado à obesidade.

Markers of redox imbalance in the blood of hypertensive patients of a community in Northeastern Brazil.

BACKGROUND: Recent studies describe the participation of reactive oxygen and nitrogen species in hypertension. OBJECTIVE: To identify the redox imbalance in the blood of hypertensive. METHODS: Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione (GSH), vitamin C, transferrin, ceruloplasmin, malondialdehyde (MDA) and carbonyl group were quantified in the blood of 20 hypertensives and 21 controls. The individuals had a Body Mass Index of ≥ 18.5 and ≤ 30 kg/m(2), glycemia ≤ 100 mg/dL, serum cholesterol ≤ 200 mg/dL, and were nonsmokers, non-pregnant and non-lactating women, non-users of alopurinol and probucol, with hypertensives on antihypertensive medication. All individuals underwent a preparatory period of 4 weeks without alcohol, vitamin supplements, dexamethasone and paracetamol. RESULTS: Reduced levels of CAT (p 0.013), GSH (p 0.003) and MDA (p 0.014), and high levels of GPx (p 0.001) and ceruloplasmin (p 0.015) were obtained in the hypertensive group compared with controls. A positive correlation between systolic pressure and MDA in hypertensive and diastolic pressure and CAT in controls was obtained. CONCLUSION: The data obtained suggest that the hypertensives were in redox imbalance, despite the possibly attenuating effect of their antihypertensive medication.

Relação da obesidade com a pressão arterial elevada em crianças e adolescentes / Relationship of obesity with high blood pressure in children and adolescents

FUNDAMENTO: Excessos de peso e de gordura corporal são atualmente reconhecidos como os maiores determinantes da elevação da pressão arterial em crianças e adolescentes. OBJETIVO: Identificar associação e correlação entre obesidade - identificada por meio da circunferência da cintura (CC), da prega cutânea do tríceps (PCT) e do índice de massa corporal (IMC) - pressão arterial elevada (PAE) em crianças e adolescentes. MÉTODOS: Estudo epidemiológico transversal, de base populacional escolar, em crianças e adolescentes de ambos os sexos, com idades entre 7 e 17 anos, selecionados aleatoriamente. Protocolo: questionário estruturado; medidas de peso, altura, espessura da prega tricipital, circunferência da cintura, pressão arterial; diagnóstico de obesidade por meio de IMC, PCT e CC; diagnóstico de PAE. Análise estatística: qui-quadrado. RESULTADOS: Foram avaliados 1.253 estudantes (547 do sexo masculino, média de idade 12,4 ± 2,9 anos), e identificou-se uma prevalência de obesidade (IMC, PCT, CC), respectivamente, de 13,7 por cento, 14,8 por cento e 9,3 por cento. A PAE foi identificada em 7,7 por cento dos jovens. Houve associação significante de obesidade (IMC, PCT, CC) com PAE (*p < 0,0001). Observou-se correlação forte (*p < 0,01) entre CC e IMC; moderada entre CC e PCT, CC e PAS, IMC e PAS (*p < 0,01); fraca entre PAD e CC, PCT e IMC, e entre PAS e PCT (*p < 0,05). CONCLUSÃO: A associação e correlação significantes entre PAE e excesso de gordura corporal por qualquer dos métodos utilizados estabelecem a importância de sua utilização na avaliação de crianças e adolescentes, com vistas à prevenção da HAS nessa faixa etária, sugerindo-se, para isso, a utilização do IMC associado a, pelo menos, um outro método antropométrico.

BACKGROUND: Excess weight and body fat are currently recognized as the major determinants of high blood pressure in children and adolescents. OBJECTIVE: To identify the relationship between obesity - identified by waist circumference (WC), triceps skinfold thickness (TSF) and body mass index (BMI) - high blood pressure (HBP) in children and adolescents. METHODS: A cross-sectional epidemiological study based on school population in children and adolescents of both sexes, aged between 7 and 17 years, randomly selected. Protocol: a structured questionnaire; measures of weight, height, triceps skinfold thickness, waist circumference, blood pressure, diagnosis of obesity through BMI, TSF thickness and waist circumference; diagnosis of HBP. Statistical analysis: Chi-square. RESULTS: A total of 1,253 students (547 males, mean age 12.4 ± 2.9 years), were assessed. A prevalence of obesity (BMI, TSF thickness, WC) of 13.7 percent, 14,8 percent and 9.3 percent respectively were identified. HBP was identified in 7.7 percent of young people. There was a significant association between obesity (BMI, TSF thickness, WC) with HBP (*p < 0.0001). There was a strong correlation (*p < 0.01) between WC and BMI, a moderate correlation between WC and TSF thickness, WC and SBP, BMI and SBP (*p < 0.01); weak correlation between DBP and WC, TSF thickness and BMI, and between SBP and TSF thickness (*p < 0.05). CONCLUSION: The significant correlation and association between HBP and excess body fat by any of the methods used establish the importance of its use in evaluating children and adolescents, aiming at preventing hypertension in this age group, suggesting, for this, the use of BMI associated to at least another anthropometric method.

[Prevalence of overweight and obesity in children and adolescents from the city of Maceió (AL)]. / Prevalência de sobrepeso e obesidade em crianças e adolescentes da cidade de Maceió.

OBJECTIVE: To establish prevalence of overweight and obesity in children and adolescents from the city of Maceió, Alagoas, Brazil, and investigate the association of risk of overweight and obesity with gender, age and type of school. METHODS: This was a cross-sectional study. Students between 7 and 17 years of age were selected from 396 public and private schools of Maceió. After randomization, data were collected by questionnaire. Weight and height were measured (body mass index = weight:height2). Overweight and obesity were defined, respectively, as body mass index greater than the 85th percentile and equal or greater than the 95th percentile for age and gender. RESULTS: The final sample included 1253 students (706 females). One hundred sixteen students were overweight and fifty six students were obese. Obesity was significantly associated with students between 7 and 9 years of age, when compared to the 10 and 13 year olds (p<0.04) and the 14 and 17 year olds (p<0.02). Private school students were more likely to be overweight (OR=2.2; CI95%:1.36 - 3.32) and more likely to be obese (OR=4.7; CI95%:2.32 - 9.34) than students CONCLUSION: The prevalence of overweight and obesity were, respectively, 9.3% and 4.5%. Overweight and obesity were significantly more frequent among private school students.

STATISTICAL ANALYSIS: Chi-square. RESULTS: A total of 1,253 students (547 males, mean age 12.4 +/- 2.9 years), were assessed. A prevalence of obesity (BMI, TSF thickness, WC) of 13.7%, 14,8% and 9.3% respectively were identified. HBP was identified in 7.7% of young people. There was a significant association between obesity (BMI, TSF thickness, WC) with HBP (*p < 0.0001). There was a strong correlation (*p < 0.01) between WC and BMI, a moderate correlation between WC and TSF thickness, WC and SBP, BMI and SBP (*p < 0.01); weak correlation between DBP and WC, TSF thickness and BMI, and between SBP and TSF thickness (*p < 0.05). CONCLUSION: The significant correlation and association between HBP and excess body fat by any of the methods used establish the importance of its use in evaluating children and adolescents, aiming at preventing hypertension in this age group, suggesting, for this, the use of BMI associated to at least another anthropometric method.

Prevalência de sobrepeso e obesidade em crianças e adolescentes da cidade de Maceió / Prevalence of overweight and obesity in children and adolescents from the city of Maceió (AL)

OBJETIVO: Estabelecer a prevalência de sobrepeso e obesidade em crianças e adolescentes de Maceió (Alagoas, Brasil) e verificar associação destes fatores com gênero, idade e tipo de escola. MÉTODOS: Estudo epidemiológico descritivo, transversal. Avaliou jovens de 7 a 17 anos de idade, sorteados das 396 escolas públicas e particulares de Maceió. Após a randomização, os dados foram coletados por meio de questionário e medidas antropométricas (Índice de Massa Corporal = peso: altura²). Sobrepeso e obesidade foram definidos como Índice de Massa Corporal superior ao percentil 85 e igual ou superior ao percentil 95 para idade e sexo, respectivamente. RESULTADOS: A amostra final foi constituída de 1253 estudantes (706 do gênero feminino). Identificados 116 estudantes com sobrepeso e 56 estudantes com obesidade. Houve associação significante entre obesidade e estudantes com idade de sete a nove anos quando comparados com os de 10 a 13 anos (p<0,04) e com os de 14 a 17 anos (p<0,02). Estudantes das escolas particulares apresentaram o dobro de chance de terem sobrepeso (OR=2,2; IC95 por cento:1,36-3,32) e aproximadamente cinco vezes mais chances de apresentarem obesidade (OR=4,7; IC95 por cento:2,32-9,34) em relação aos das escolas públicas. CONCLUSÃO: As prevalências do sobrepeso e obesidade foram de 9,3 por cento e 4,5 por cento respectivamente, sendo significantemente mais elevadas em estudantes das escolas particulares.

OBJECTIVE: To establish prevalence of overweight and obesity in children and adolescents from the city of Maceió, Alagoas, Brazil, and investigate the association of risk of overweight and obesity with gender, age and type of school. METHODS: This was a cross-sectional study. Students between 7 and 17 years of age were selected from 396 public and private schools of Maceió. After randomization, data were collected by questionnaire. Weight and height were measured (body mass index = weight:height2). Overweight and obesity were defined, respectively, as body mass index greater than the 85th percentile and equal or greater than the 95th percentile for age and gender. RESULTS: The final sample included 1253 students (706 females). One hundred sixteen students were overweight and fifty six students were obese. Obesity was significantly associated with students between 7 and 9 years of age, when compared to the 10 and 13 year olds (p<0.04) and the 14 and 17 year olds (p<0.02). Private school students were more likely to be overweight (OR=2.2; CI95 percent:1.36 - 3.32) and more likely to be obese (OR=4.7; CI95 percent:2.32 - 9.34) than students CONCLUSION: The prevalence of overweight and obesity were, respectively, 9.3 percent and 4.5 percent. Overweight and obesity were significantly more frequent among private school students.

Trombo em trânsito no interior do átrio direito: relato de caso e revisão da literatura / Right heart emboli-in-transit: case report and literature review

Trombos móveis no átrio direito são raros e associados a altas taxas de embolia pulmonar e de mortalidade. Neste relato é apresentado um caso de trombo em trânsito nas câmaras direitas, com suspeita clínica de tromboembolismo pulmonar, diagnosticado por ecocardiografia transesofágica, com boa evolução após anticoagulação. São também discutidas suas formas de apresentação, tratamento e evolução.

Emboli in transit in right atrium are rare. When they occur, they are associated to high rate of pulmonary embolism and mortality. This is a case report on an embolus in transit in right chambers, with clinical suspicion of pulmonary thromboembolism. Diagnosis was obtained through transesophageal echocardiography. The patient had a positive response post-anticoagulation. The team discussed presentation forms, treatment and condition development.

Congenital heart diseases in the newborn: from the pediatrician's request to the cardiologist's evaluation.

OBJECTIVE: To analyze the importance of symptoms as a reason for referral to pediatric cardiologists in the diagnosis of congenital heart diseases (CHD) in the newborn (NB). METHODS: Prospective study on live NB referred for cardiac evaluation, with performance of electrocardiogram, chest radiography and echocardiography. Cardiology consultation was requested by means of a multiple-choice form including signs and symptoms suggestive of CHD. Patent ductus arteriosus (PDA) without clinical and/or hemodynamic consequences was not considered a heart disease. RESULTS: From 1999 to 2002, 358 out of 3716 NB were studied, and 49 cases of CHD and 128 of PDA were found. The prevalence of CHD was 13.2:1000 NB. The main reason for referral to the cardiologist was heart murmur in 256 (72%) NB, of which 39 (15%) had CHD, and in 91% of the 128 cases of PDA. In 14 (4%) NB, the reason for referral was cyanosis, and eight of these patients (57%) had a CHD. Heart failure was the reason for referral in 37 (10%) NB, of whom 17 (46%) had CHD. Arrhythmia, associated congenital malformations, or chromosome disorders were the reasons for referral in 14% of the cases. CONCLUSION: The main reason for referral was detection of a heart murmur on cardiac auscultation. Although cyanosis and heart failure were uncommon reasons for referral, their presence indicated a high probability of the diagnosis of heart disease. Pediatric screening plays a key role in this diagnosis.
